Most Optimal Selection™ Feline results arrive around 2-3 weeks after our lab receives your cat's DNA sample. That said, extended times sometimes occur due to circumstances beyond our control (e.g., volume at the lab, holidays, illnesses, natural disasters). You'll get an email notification when your results are ready. Please note—results are digital and available in your online account only. No physical report will be mailed, but you may download a printable technical report from your account.
Once we receive your cat’s sample, we scan it into our system and assign it to a batch for testing. We then extract the DNA, and screen for markers associated with disorders, traits, and diversity. It normally takes 2-3 weeks from the time our lab receives a sample to complete the genetic testing and analysis.
Yes! Optimal Selection™ Feline is available to all Canadian customers (except those in the province of Quebec, due to packaging requirements). Canadian kits ship via UPS to reduce customs delays. Shipping is $15 USD for the first kit and $5 USD for each additional kit per order. All prices are listed in USD but converted to CAD upon payment.
Not to worry! Transit times vary throughout the year due to several factors (e.g., holidays, weather, natural disasters) and may take anywhere from 5-10 business days. When samples arrive at our lab, we check them in individually to avoid contamination or mix-ups. Once we begin processing your sample, the status will change to "Sample Received," and you will be alerted via email. If you would like to track your sample while it's in transit to our lab, please note the USPS tracking number on your kit’s prepaid shipping label before putting it in the mail.
Weather is unlikely to impact sample quality. Cheek cell samples are a very stable way to collect DNA for testing, and they can withstand normal ambient temperature changes.
You can track the progress of your sample online by signing into your account.
The USPS tracking will show when the package gets delivered to the post office in Lincoln, NE. From there, the kits travel via courier to the lab on the next business day. Each kit is then checked in individually to avoid any risk of contamination. For these reasons, there will sometimes be a delay of a few days between delivery and sample processing. Rest assured, this additional time has not been found to affect sample quality at all.
Yes. Designed for cats of all ages, the Optimal Selection™ Feline test is safe and easy to use at any stage in a cat’s life. That said, we recommend waiting until a kitten has been weaned to prevent cross-contamination from skin and other cells within the mother’s milk.
DNA testing can be performed on a cat of any age, and Optimal Selection™ results will not change with age. Blood samples may be taken from kittens as soon as they are large enough for a veterinarian to obtain 1-2 mLs of blood (less than one teaspoonful) safely. Swab samples can also be taken from young kittens, but it’s best to wait until the kitten is weaned (to prevent contamination from the queen’s milk or skin) or nursing infrequently enough that a cheek sample may be taken three hours after last nursing or food.
Worried about DNA cross-contamination skewing results? Don’t be! As a quality control measure, our computer alerts us when a sample contains markers from more than one individual. (Another red flag is the presence of DNA from different species entirely. For example, the domestic cat has 19 chromosome pairs and a specific genetic structure that’s quite different from that of a canine, which has 39 pairs.) In such an event, samples typically fail and we would send you fresh swabs so you can collect a new sample. If you suspect contamination due to unexpected results, or if you think your cat’s sample may be contaminated and haven’t mailed it in yet, please email breeder@wisdompanel.com to discuss.
Yes, you would receive personalized results for your non-pedigreed cat for disorders, traits and diversity as compared to all cat breeds, with no breed-specific information or ancestry provided. However, for non-pedigreed cats in the United States, we have an ancestry product which also includes most of the same test results, called Complete for Cats, which can be found on our Wisdom Panel website, here: www.wisdompanel.com
Simply follow the provided instructions to collect a sample from the inside of your cat's cheek with the included swabs. (If you have additional questions about sample collection, please see our guide.) Then, using the "Test Sample ID" on your kit’s box, activate your kit online and mail the swabs back to our laboratory in the postage-paid packaging. Approximately 2-3 weeks after the sample arrives at our lab, you'll get an email letting you know that your report is ready to view in your account at www.optimal-selection.com
We recommend the two-hour waiting period to reduce the risk of food particles encouraging bacterial growth on the swabs. If you can see food particles on the swab or have concerns about the sample, please contact our customer service team at breeder@wisdompanel.com.
Sampling documentation is needed to verify that the samples have been taken officially by a veterinarian when official test results are required by a cat registry or a breed club. We recommend that our customers keep the signed sampling documentation to themselves to be able to show it to the authorities together with the test results when requested.

ISAG 2020 Profiling and Parentage testing service is available with Optimal Selection™ Feline testing as an add-on or bundle! To learn more about our DNA profiling check here, and for information about our parentage service check here. Samples that were processed on or after January 1, 2021 are eligible for upgrade. Older samples were run on older technology so a new sample would be needed in order to obtain parentage and profiling results.
No. ISAG 2020 DNA profiling is only available bundled with MyCatDNA™ or Optimal Selection™ Feline, or as an upgrade to MyCatDNA™ or Optimal Selection™ reports submitted after January 1, 2021.
DNA profiling is $49 as an upgrade, or purchased as a bundle for $148.99. Please note that the cat must have an ISAG 2020 DNA profile with Wisdom in order to perform parentage analysis. Parentage analysis is complimentary for cats within the same user account with ISAG 2020 DNA profiles on file.
Not necessarily. Cats tested after January 1, 2021 are eligible for upgrade purchase. Older MyCatDNA™ and Optimal Selection™ tests lack the necessary markers to be compatible with the current ISAG 2020 testing panel. An upgrade option will appear under the Reports tab as “Unlock DNA Profiling” if your cat is eligible.
Log in to your account at https://www.wisdompanel.com/app/ and click on the cat you wish to upgrade. Under the “Reports” tab, if your cat is eligible for an upgrade without retesting and does not already have a current DNA profile with Wisdom, an “Unlock DNA Profiling” section will appear, with instructions to upgrade. Wisdom Panel™ ancestry tests are not eligible for DNA profiling at this time.
Cats must be tested with Optimal Selection™ or MyCatDNA™ after January 1, 2021 to be eligible to upgrade to DNA profiling. Upgrade instructions will appear under the “Reports” tab. Wisdom Panel™ ancestry tests are not eligible for DNA profiling at this time.
We are working on a solution for those who chose the wrong test type to convert to a Wisdom breeder test type for DNA profiling, but it is not available now.
ISAG 2020 DNA profiling is available exclusively for Wisdom breeder test types (Optimal Selection™ or MyCatDNA™).
Wisdom is proud to use the most advanced internationally recognized profiling and parentage panel recommended by the International Society for Animal Genetics (ISAG) for cats, ISAG 2020, which utilizes a 101 marker SNP panel. ISAG is the animal genetics governing body responsible for standardization of domestic animal DNA profiling and parentage.
Wisdom takes pride in the accuracy and repeatability of our results. Wisdom breeder DNA profiling utilizes the ISAG 2020 panel, the newest profiling and parentage panel recommended by International Society for Animal Genetics (ISAG) for cats. We consistently receive top-of-class genotyping accuracy rank when our performance is tested by ISAG.
Yes. Wisdom geneticists are members of ISAG and helped develop and validate the newest internationally-recognized panel currently recommended by ISAG, ISAG 2020. We consistently receive top-of-class genotyping accuracy rank when our performance is tested by ISAG.
Our profiles are compatible with testing labs using ISAG 2020, the newest SNP panel recommended by the International Society for Animal Genetics.
Yes, Optimal Selection™ and MyCatDNA™ DNA profiling results are accepted by TICA in most cases.
Registries vary in their requirements, so please check with them. Ask if ISAG 2020 SNP profiling is accepted, and if there are any requirements for sample collection, such as veterinary verified collection and chain of custody for the sample which must be followed for results to be recognized.
Yes, DNA profile samples collected during pregnancy are accurate as the amount of circulating fetal DNA present in a blood sample is negligible, and not present for cheek swab samples.
Cheek swab (buccal mucosal) samples and whole EDTA blood are considered standard sample types for DNA profiling. Non-traditional samples such as semen and soft tissue can be submitted. Requirements are minimum 50 microliters semen (used semen straw does not provide adequate DNA, must be unused straw/pellet), and frozen, not fixed, approximately sugar cube size soft tissue samples. Please contact us in advance for arrangements. Special shipping requirements and charges apply for non-traditional samples, and no refunds are provided in the event of sample failure. Please contact our customer service team for details at breeder@wisdompanel.com.
DNA profiling should be available in 2-3 weeks after receipt at the laboratory if ordered at the time of your MyCatDNA™ or Optimal Selection™ kit . You should get an email notification when your sample has arrived at the lab, and again when results are ready. You can also log into your account to check the status and view the DNA profile certificate when completed.
Please note—due to the digital nature of our product your results will be available in your online account only. No physical report will be mailed.
In order to ensure the highest quality, there is no way to expedite the lab process at this time. This means that if you need DNA profiling right away, please be sure to give plenty of time for shipping and processing. Once received at the lab samples generally take 2-3 weeks for processing.
We consider the owner of the DNA profiling results to be the person submitting the sample of the cat. Please ensure you’ve obtained all necessary permissions prior to submitting a sample for DNA profiling if it is not legally your cat.
Yes. A minimum of 50 microliters is required for semen samples, so used semen straws do not provide adequate DNA; it must be an unused straw/pellet. Please contact us in advance for arrangements. Please contact us in advance for arrangements. Special shipping requirements and charges apply for non-traditional samples, and no refunds are provided in the event of sample failure.

Special shipping requirements and charges apply for non-traditional samples, and no refunds are provided in the event of sample failure. Please contact our customer service team for details at breeder@wisdompanel.com.
No. Account owners are responsible for sharing results with their registry if needed. We have a strict privacy policy that requires written consent from the cat owner (as submitted during kit activation) before we may share any information about testing with anyone who is not listed on the account, including registries and associations. For this reason, reports are emailed only to the email address on file. If the sample was submitted through your registry, and you gave permission to share results as part of that submission process, we may share the results to your registry.
Yes, we accept purified, archived DNA and frozen semen for deceased cats. A minimum of 50 microliters is required for semen samples, so used semen straws do not provide adequate DNA; it must be an unused straw/pellet. If using archived DNA from another lab, please contact us in advance to arrange the sample transfer. Special shipping requirements and charges apply for non-traditional samples, and no refunds are provided in the event of sample failure. Please contact our customer service team for details at breeder@wisdompanel.com.
Veterinary collection and veterinary verification are not required to submit a sample for DNA profiling and receive results. However, results may not be accepted by all registries or associations without specific sample collection and handling. Please check with your registry in advance for their requirements. Wisdom breeder products do not currently support vet verified samples.
We can offer parentage testing if your cat has had ISAG 2020 profiling performed by Wisdom. Cats tested on Optimal Selection™ or MyCatDNA™ after January 1, 2021 are eligible for upgrade. Older DNA profiles and samples lack the necessary markers to be compatible with the current ISAG 2020 testing panel. An upgrade option will appear under the Reports tab as “Unlock DNA Profiling” if your cat is eligible. If your cat is not eligible for a DNA profile upgrade, a new sample must be submitted.
We cannot accept DNA profiles from other laboratories at this time, regardless of type.
Yes! Historically, DNA profiles for both parents were required to complete the analysis. However, due to the size and robustness of the new ISAG 2020 panel, single-parent or one-sided parentage analyses can be performed if necessary. For highest confidence, we still recommend testing both parents, and if the mating is in a very low genetic diversity breed or the breeding was of closely related cats, single-parent analysis is not advisable.
We do not! Historically, DNA profiles for both parents were required to complete the analysis. However, due to the size and robustness of the new ISAG 2020 panel, single-parent or sire-only parentage analyses can be performed if necessary. For highest confidence, we still recommend testing both parents, and if the mating is in a very low genetic diversity breed or the breeding was of closely related cats (e.g. dual sires that are siblings), single-parent analysis is not advisable.
Our system does not currently support parentage analysis if the DNA profile is under a different account. We hope to add this feature in the future.
There are two common submission errors. The most common is that there was a typo or an update that must be made regarding your cat’s information (e.g. from “Unregistered Kitten #1” to “Registered Name”). Some fields cannot be edited except by Customer Service, in order to reduce risk of fraud. Please email us your request at breeder@wisdompanel.com if you need this information updated.
Another type of error is that the sample as it was submitted was activated or labeled as another cat. This usually occurs at home, most often swapped with another cat sampled and submitted at the same time. If you suspect this is the case, contact Customer Service at breeder@wisdompanel.com to determine the nature and scope of the problem so it can be corrected.
If you realize there is a problem after generating parentage testing reports and suspect a different sample error, please contact Customer Service to discuss and determine a plan to correct the problem.
If you realize after parentage testing that your pedigree is incorrect, please notify Wisdom prior to contacting your registry if you will need to update your cat’s pedigrees, so we can answer any questions you might have and conduct a secondary analysis if needed. There is a rare exception in which parentage testing provides a conflicting result called chimerism, in which the parent has more than one set of DNA in their body, and the DNA in their sperm/ova does not match the DNA in their blood or cheek swab sample.
Updates to cat name will automatically update in the parentage report if you contact customer service to correct. We currently do not support editing of manually-entered breeder or owner name associated with parentage report generation once that particular parent-offspring parentage combination analysis has been completed.
Parentage testing is no additional charge! Please note that the cats to be tested must have an ISAG 2020 DNA profile with Wisdom in order to perform parentage analysis. Parentage analysis is complimentary for cats within the same user account with ISAG 2020 DNA profiles on file.
Parentage analysis typically takes less than 1 minute. When the report is ready, you will receive an email and also find it archived in your “Reports” tab for viewing or download.
No. We recommend always testing cats that will be bred. It is best to leave relying on "Clear by parentage" for pets or cats that won't be bred.
Wisdom Health began work with the feline breeder community in 2015 to develop a comprehensive DNA analysis for feline breeders to help make informed breeding decisions. Based on this work, Optimal Selection™ Feline was launched in November 2016, and MyCatDNA™ in 2018.
Optimal Selection™ Feline and MyCatDNA™ tests are the world’s most comprehensive cat DNA tests. So, your cat’s results can certainly help you take better care of them and make informed breeding decisions. But they’ll also empower us to improve the lives of cats everywhere for generations to come. Our scientists have been studying dog DNA for more than 20 years and cat DNA for more than five, but there's always more to learn. By testing your cat with Optimal Selection™ Feline or MyCatDNA™, you're contributing to the largest veterinary genetic research study—ever. Each test carries us closer to the next scientific breakthrough in pet health.
We understand that some of the tests included in the Optimal Selection™ Feline test may not be relevant to all breeds, but we can’t single out specific tests due to the nature of our panel testing. We’re only able to offer a panel test at the current price, thanks to volume and automation. In other words, it costs less to report on all mutations using our custom chip than it would cost to run individual tests.
At this time, the FDA and EMA do not regulate genetic tests for companion animals. So, there’s no requirement for FDA or EMA approval for the Optimal Selection™ Feline test. That said, all Optimal Selection™ Feline tests are processed in a USDA-accredited and ISO-certified laboratory for proper quality control, and our MyCatDNA™ European processing facilities follow DS/EN ISO/ IEC 17025:2005 standards. We’re also regularly peer-reviewed and audited by independent experts who are leaders in their respective fields to ensure we deliver world-class genetic screening.
The old reports are still available in your account and should have all the tests that were available when the panel was originally processed. To find the original (legacy) report select “manage pet profile” under the cat in question and scroll down to the bottom of the page; the PDF link for the legacy report can be found there. When older tests were migrated to the new platform, only tests that are performed in the same manner now as they were then could be moved over; otherwise the specific test information on the details page would be incorrect. Some of the tests in question are Colorpoint Siamese (cs) and Pyruvate Kinase Deficiency (PK Def).
No. A new sample will be needed in the event you wish to update results on a previously tested cat, as all new genotyping will need to be performed.
More than 3 million pet parents worldwide have chosen Wisdom Health Genetics, the world leader in pet genetic testing, and we have offered feline genetic testing for breeders since 2016. In our long history of testing dogs and cats, we’ve implemented quality controls to ensure at least 99% accuracy for our health tests. And to ensure quality control, all cat breeder tests in the US and Canada are processed by a USDA-accredited laboratory.
Each kitten in a litter starts as a unique egg and sperm—much as fraternal twins do in humans. Documented instances of identical twins in cats are rare, so cat siblings are approximately 50% genetically related if they share both parents. But if more than one tom sires a litter, each kitten can have a different father. This would make the kittens half-siblings and only about 25% genetically related. In such cases, littermate kittens could have very dissimilar results. Another reason their results may differ has to do with which exact segments of DNA they inherit. Though each parent is responsible for passing down 50% of their genetic make-up to a kitten, the actual composition of that genetic contribution varies between siblings. This is due to the random nature of gene inheritance and a process known as “genetic recombination.”
No. Although mutations can occur within individual cells throughout life, a cat’s DNA does not change with age. Some specific tests may be added or removed as technology changes.
Yes, we are able to see your cat's genetic sex in the raw report data. But their results will default to showing the gender you enter when activating the test kit.
Currently, there is no clinically validated, commercially available method for determining a pet’s age using genetics. But your veterinarian may be able to provide an age estimate upon examination.
The Optimal Selection™ Feline DNA test is neither designed nor intended to determine or validate whether your cat is purebred. We recommend if you wish to have your cat registered with a pedigree that you contact a registry, such as TICA or CFA, to learn more.
Genetics are complex, and it’s common to have questions. To ensure you’re confident in your cat’s results, we’re happy to go through them with you and have the data reviewed, if necessary. Please contact us at breeder@wisdompanel.com.
Our list of disease-causing disorder tests is always growing. For the most up-to-date information, please reference our product page.
Not necessarily. A cat that’s "at risk" for a disease-causing genetic mutation usually has one copy of a dominant mutation or two copies of a recessive mutation (although, there are a few exceptions), but they may never show clinical signs of the disease. The Optimal Selection™ Feline test does not provide a clinical diagnosis. Rather, it’s meant to give you and your veterinarian advanced warning for potential conditions so you may watch for signs and diagnose conditions early.
The Optimal Selection™ Feline test returns one of three results: clear, notable, or at risk. Here’s what each label means.
In both cats and dogs, the Multi-Drug Resistance 1 (MDR1) gene is responsible for the production of a protein called P-glycoprotein—a transport pump that helps limit the absorption and distribution (particularly to the brain) of many veterinary medications. But a mutation in this gene may cause the pump to malfunction, resulting in adverse reactions to common medications. If your cat tests positive for the MDR1 mutation, it’s important to tell your veterinarian so they can plan your cat’s care accordingly. For example, they may prescribe lower doses of certain drugs or avoid others entirely.
Optimal Selection™ Feline tests for two variants of Hypertrophic Cardiomyopathy (HCM), the A31P mutation found in the Maine Coon, and the R818W (previously R820W) mutation found in the Ragdoll. Both variants are located in the MYBPC3 gene. However, HCM has also been found in about 5.4% of Maine Coons negative for A31P, thus indicating that this mutation is not the sole cause of HCM in Maine Coons, and other genetic variants contributing to the risk of HCM are likely. Because HCM cannot be reliably detected by routine examination, lines or breeds suspected to be at risk of HCM should be examined at least once a year by a veterinarian, preferably a cardiologist, and an echocardiogram (heart ultrasound) used for screening, definitive diagnosis and characterization of severity.
As Optimal Selection™ Feline is a panel test, the submitted cat’s sample will be tested against all reportable health disorders regardless of the breed indicated by the owner. The PKD1 variant included in the current panel behaves in an autosomal dominant manner and is historically associated with PKD in Persians and Persian-derived breeds. It has also been found associated with PKD in other breeds, such as the Chartreux, Maine Coon, Siberian (Neva Masquerade) and random-bred cat family lines, indicating the PKD1 variant can cause PKD independent of the breed background. It is worth noting that there appears to be other unknown causes of PKD, at this time.
There are two known variants for Factor XII deficiency. In 2020, the second variant was added to Optimal Selection™ Feline which resulted in a renaming of the variants for clarity. What was formerly called Factor XII deficiency has now been renamed Factor XII Deficiency, Variant 1. The following key may be helpful:
Breeder Reports
Prior to October 2020
Breeder Reports
October 2020-Present
Factor XII deficiency
Factor XII deficiency (Variant 1)
---
Factor XII deficiency (Variant 2)
We have found that Variant 2 is more widespread than Variant 1. If a kitten was tested after October 2020 and found to carry Factor XII deficiency, and its parents tested clear prior to that time, the likely cause is Variant 2. The parents can be retested to verify Factor XII Deficiency (Variant 2) status if desired.
Currently, the Optimal Selection™ Feline test does not test for the Red gene. This gene produces the orange coat coloration known as yellow, ginger, and marmalade. But its precise location is yet to be published in the scientific literature.
Optimal Selection™ Canine screens for over 50 traits. View the complete list of coat color tests here.
The genetics of traits can be very complicated. It’s common for a cat to carry an appearance gene that’s not expressed because other traits override it. For instance, a solid white cat may carry the genes for a tabby patterning and coat color dilution. But you wouldn’t know it because the white removes all the pigment from the affected area of the coat—essentially hiding any color or pattern underneath.
Currently, the Optimal Selection™ Feline test does not test for the Red gene. This gene produces the orange coat coloration known as yellow, ginger, and marmalade. But its precise location is yet to be published in the scientific literature. That said, we know the dominant Red gene is located in the X chromosome, and the mutation hides other pigments of the coat. Ginger cats are typically males with only one X chromosome. Tortoiseshell and calico (a red patched pattern on the coat) cats are almost always female. Female cats have two X chromosomes, but a process called X chromosomal inactivation causes only one per cell to be active. Depending on which versions of the Red gene are present in the active X chromosomes, an area of the cat’s coat may be red or any other color that the Red mutation hides. Only white (technically the absence of pigment) can hide red pigment expression.
The most common cause of tabby markings in a cat testing as solid colored (a/a) is if the cat also carries Dominant Red/orange. The dominant red gene “turns off” the effects of solid coloring, allowing tabby markings to be shown. This phenomenon is called epistasis. Therefore, tortoiseshell, calico, and solid orange cats will always show tabby markings in the orange portions of their coat. MyCatDNA® and Optimal Selection™ Feline do not currently test for orange.
MyCatDNA® and Optimal Selection™ Feline do not currently test for modifiers of tabby patterning, but we are working on it!
Blue eyes are classically caused by a lack of pigment within the iris, or colored portion of the eye. All kittens are born blue-eyed, only to gain their true eye color around six weeks of age. But for cats whose eyes stay blue, one of three known genetic factors could be at play. In some cat pedigrees, blue eyes tend to be “fixed,” or predictable. This is especially true in breeds with color points, as a recessive albinism gene is what causes their coat color restriction. Other cats may have white fur (which is actually a lack of color pigment) around the eye. This produces an effect similar to albinism, and it can also result in odd eyes, or heterochromia—when a cat has one blue and one pigmented eye. Cats with Dominant White may also have varying degrees of hearing impairment. Lastly, a dominant blue eye (DBE) variant was discovered in the PAX3 gene in 2024 that accounts for the blue eyes seen in the Celestial cat breed (DBECEL), and other DBE variants are suspected in the Topaz, Altai and Ojos Azules breeds.
Optimal Selection™ Feline tests for three variants responsible for polydactyly, or extra toes, on the front or all four feet. However, cats with one copy of one of the variants have about a 50% chance of having extra digits. Cats with two copies of this variant are even more likely to have extra toes, but even then, in some cases, they will have no extra digits.
Optimal Selection™ Feline tests for three variants responsible for polydactyly, or extra toes, on the front or all four feet. However, other variants are suspected to cause polydactyly in certain breeds (e.g. Maine Coon) which are currently unknown.
Optimal Selection™ Feline tests for three known variants responsible for natural bobtail, but other variants are known to exist. If your cat has a short tail but is negative for one of these variants, he or she may be carrying another variant causing bobtail, or in some cases, trauma or other causes may result in a shortened tail.
Optimal Selection™ Feline tests for two known variants responsible for Lykoi coat, but other variants are likely to exist. Two copies of any Lykoi variant are required to show this coat type. If your cat has a Lykoi coat type but was found to carry 0 or 1 copy of these variants, he or she may be carrying another variant causing the Lykoi coat type.
Optimal Selection™ Feline currently tests for one variant of hairlessness; one of the forms found in the Sphynx, but other variants are known to exist. Notably, the cause of hairlessness found in the Russian breeds Donskoy (Don Sphynx) and Peterbald is yet to be discovered.
Optimal Selection™ Feline tests for two variants of rexing, that of the Cornish and German Rex, and the Devon Rex. The previously reported Selkirk Rex genetic variant has become challenging to test using the technology of Optimal Selection™ Feline with recent updates to our testing process. Because of this, we have chosen to halt reporting on this trait until a more robust assay can be developed. If your cat’s rexing is caused by the variant found in the Selkirk Rex or from another variant, such as demonstrated by the Tennessee Rex, your report will indicate a normal coat is likely because these are different genetic variants than those being tested at this time.
Optimal Selection™ Feline does not currently test for variants associated with the coat pattern known as Ticking, which is characterized by multicolored or multiple (e.g. 2-3) bands of color on the hair shaft. Ticking appears to be epistatic to, or mask, most tabby markings, showing only the agouti pattern if the cat is non-solid. It is most commonly seen in the Abyssinian, Somali, Singapura and Asian breeds, but can also occasionally be seen in random-bred cats.
Wisdom Health™ is committed to providing trustworthy results to breeders. With recent updates to our testing process, and because this particular genetic variant is challenging to test using the technology of Optimal Selection™ Feline, we have chosen to halt reporting on this disorder until a more robust assay can be developed.
Much like humans, cats can be split into blood types: A, B, and AB (sometimes called Type C). Genetic contributions from a cat’s mother and father determine their blood type. But unlike humans, cats have no universal donor blood type. And if a cat receives a non-compatible blood type during a blood transfusion, it may cause a severe, life-threatening reaction. But that’s not the only time blood type matters. For example, when kittens are nursing from their mother, they receive some of her antibodies from her milk. And if the mother cat’s blood type is different from that of her kittens, her antibodies may destroy their red blood cells. For these reasons, knowing your cat’s blood type—and sharing that information with your veterinarian—is critically important. The Optimal Selection™ Feline test identifies four genetic variants which influence feline blood types and have been shown to be 99% consistent with serologic blood type in domestic cats. Cats carrying undetermined, new, or undiscovered variants or other genes may have a different blood type compatibility than what the test reports.
The Cat Blood Type feature is now available for all users with the new web experience and it can be found at the bottom of the Health tab.
Optimal Selection™ Feline’s DNA-based blood type determination screens for four genetic variants determining blood group AB in pedigreed cats in accordance with the latest scientific literature. Wisdom Health™’s own research confirmed that a genetic variant resulting in blood type B in Turkish breeds significantly improved DNA-based blood type testing in the European Shorthair, Siberian cat, Turkish Angora and Turkish Van, and also increased the accuracy of DNA-based blood typing in over 10 different breeds. Reporting for this variant began in 2018, and is now called b variant 2. The genotyping for an additional third genetic variant resulting in blood type B in Ragdoll was confirmed by Wisdom Health™’s own research and genetic testing for this variant has been offered since October 2021 as a part of the Optimal Selection™ Feline test, now called b variant 3. B variants have been renamed in current reports to reflect these additions. We will continue both in-house research efforts as well as monitoring of outside research findings to ensure that your cat’s blood type results are based on the most current understanding of this complex subject. Reports continue to return blood type A, B, or AB based on these findings. The following table summarizes reporting changes:

The genetic diversity measurement found in Optimal Selection™ is based on genotyping specific single nucleotide polymorphisms (SNPs) of the genome and calculating the times a same (homozygous) or different (heterozygous) variant was inherited from the parents. All heterozygosity calculations in our products have been calculated based on the same SNP panel maintained on our custom microarray chip. This is notable because calculations from different sources can differ slightly due to differences in the marker sets used.
COI is typically based on recent pedigrees and is associated with the probability of inheriting two copies of the same allele (or sometimes a haplotype, being a large genomic chunk of inherited alleles) from common ancestors. Diversity (or heterozygosity) scoring is based on genetic testing at a number of genomic locations that are informative of overall variability within a population.
It’s worth noting that measuring genetic diversity is measuring an association with inbreeding, rather than directly measuring inbreeding. In addition to recent family inbreeding, Optimal Selection™ diversity score reflects long-term population “inbreeding” which can be very important in breeds that have had small, relatively closed populations for many generations. This genetic diversity measurement is most useful when comparing the score against the provided population’s score as both were created using the same method and genetic marker set.
We are exploring new and better ways to convey the information in the Genetic Relationships graphs (also known as the MDS graphs). But for the time being, they are not available.
To provide a better experience for all customers, we’re consolidating our products onto the same web platform. Due to the technical complexity of supporting the Breeder Tool for our large breeder base, it will not be available in the immediate future. But we are exploring ways to bring this functionality to our customers in future updates and will inform you when more details are available.
