Best Cat DNA Tests for Breed Ancestry and Genetic Health Screening (2026)

A cat DNA test does two jobs: it estimates where your cat's ancestry comes from, and it screens for inherited variants linked to disease. This guide compares the two cat DNA kits it found on Amazon on both jobs, and on the extras that are specific to cats: blood type and oral health. Wisdom Panel Complete for Cat ranks first for its broad ancestry report, blood type and follow-up consult. The Basepaws Breed, Health & Dental kit ranks second and is the one with an oral-health report.

The field is small. A whole-genome cat test was also considered but is not a pick here. Two kits that pass is a better answer than a padded list.

These picks are editorial synthesis. PetPalHQ does not run a genetics lab, and neither kit has been run by us. Each was chosen by reading its maker's product page and its Amazon listing against Cornell Feline Health Center and Merck Veterinary Manual guidance. Each card figure is the Amazon price on the check date shown on that card.

Health Screen, Ancestry, or Both

Both kits do both jobs, so the choice comes down to which extras you want and how much ancestry detail you need. The health screen is the part with veterinary weight behind it. Cornell says of polycystic kidney disease: "There is no explanation for the development of these cysts except for a genetic anomaly that is evident primarily in Persians and occasionally in a few other feline breeds, such as Himalayans and British Shorthairs." For heart disease, Cornell says HCM "is more prevalent in certain breeds (including Maine Coon, Ragdoll, British Shorthair, American Shorthair, Sphynx, Bengal, Chartreux, Norwegian Forest, Siberian, and Persian cats)" and that the genes found in some affected cats suggest "that genetics plays a role."

Ancestry is where the two kits differ most. Wisdom Panel says its kit screens for 70+ breeds and populations. The Basepaws listing says its kit distinguishes 20+ breeds.

What a Health Result Means, and What It Does Not

A positive result is a flag, not a diagnosis. Cornell's advice on genetic tests for HCM is direct: "New genetic tests may also help identify whether your cat has an increased risk of HCM, but the results of these screening tests should be interpreted carefully with the guidance of a veterinary professional, since not all cats that have these mutations will develop the condition."

Consumer tests can still be useful to bring to the vet. A 2022 study in PLoS Genetics says: "Direct-to-consumer genetic tests help to raise awareness of various inherited single gene conditions in cats and provide information that owners can share with their veterinarians." Note who wrote it: the authors include the Wisdom Panel Research Team, so it is not an independent view of Wisdom Panel's kit. That is one reason this guide scores follow-up help. Wisdom Panel lists a genetic consult for 'at risk' findings; for the Basepaws kit, the next step is your own vet.

Blood Type and Oral Health: The Cat-Specific Extras

Wisdom Panel's kit identifies blood type. The Merck Veterinary Manual says: "Blood type testing is performed to help decrease the risk of immunological transfusion reactions in dogs and cats." Keep the result in the cat's records and share it with your vet.

The Basepaws kit adds an oral-health report instead. Basepaws says the mix of microbes in a cat's mouth indicates the cat's risk for bad breath, tooth resorption and periodontal disease. That is Basepaws' claim about its own method. Use the report as a prompt for a dental check, not in place of one.

If you have a dog as well, the dog DNA tests guide covers dog kits; neither kit on this page tests dogs. For other ways to keep an eye on health at home, see at-home pet health monitoring tools.
