Genetic testing has revolutionized cat breeding. Conditions like Hypertrophic Cardiomyopathy (HCM) and Polycystic Kidney Disease (PKD)—once discovered only when cats became ill—can now be identified before breeding through a simple cheek swab. This guide explains why DNA testing is essential for responsible cat breeders, what conditions to screen for, and how the major testing providers compare.
- HCM and PKD are the most common inherited conditions in cats—both can be detected through DNA testing
- Blood type testing prevents Neonatal Isoerythrolysis, a fatal condition in kittens from incompatible matings
- DNA test costs range from $70-$160 per cat depending on provider and panel size
- TICA-recognized tests include Optimal Selection and MyCatDNA; CFA partners with Neogen
- Results are lifetime—test once and you’ll know your cat’s genetic status forever
What is Feline Genetic Testing?
Feline genetic testing analyzes your cat’s DNA to identify mutations associated with inherited diseases. Using cells collected from a cheek swab, laboratories scan for genetic markers linked to conditions like heart disease, kidney disease, eye problems, and blood type compatibility issues.
Unlike physical examinations that assess current health, DNA testing reveals hidden genetic information—including whether your cat carries disease-causing mutations that could be passed to kittens. A cat can carry a mutation for years without showing any symptoms, yet still pass that genetic defect to the next generation.
DNA Testing vs. Physical Screening: DNA testing identifies genetic risk, but some conditions also require physical screening. For example, HCM-negative cats can still develop the condition from non-genetic causes. Responsible breeders use DNA testing alongside regular cardiac ultrasounds.
Why DNA Testing is Essential Before Breeding Cats
Preventing Fatal Kitten Conditions
Some genetic conditions in cats are devastating—and entirely preventable through testing. Polycystic Kidney Disease causes cysts that progressively destroy kidney function. Spinal Muscular Atrophy leads to muscle wasting and death in young kittens. Pyruvate Kinase Deficiency causes severe anemia. All of these can be avoided by testing breeding cats and making informed pairing decisions.
Carriers Show No Symptoms
Most inherited diseases follow a recessive inheritance pattern. A carrier cat has one copy of the mutation and appears perfectly healthy. The cat may live a long, normal life with no visible signs of carrying a genetic defect. But when two carriers are bred together, 25% of their kittens will inherit two copies of the mutation and develop the disease.
The HCM Exception: Hypertrophic Cardiomyopathy mutations in Maine Coons and Ragdolls are autosomal dominant—meaning cats with just one copy of the mutation can develop heart disease. This makes testing even more critical for these breeds.
Blood Type Compatibility
Unlike dogs, cats have a significant blood type compatibility issue that affects breeding. When a Type B female mates with a Type A male, the kittens may be Type A—and the mother’s colostrum contains antibodies that attack Type A blood cells. This causes Neonatal Isoerythrolysis (NI), often called “fading kitten syndrome,” which is frequently fatal within the first few days of life.
DNA testing identifies blood type so breeders can avoid incompatible pairings or take precautions (like preventing nursing for the first 16-24 hours and bottle-feeding colostrum substitute).
Registry Recognition and Breeder Reputation
Both TICA and CFA encourage genetic testing. Many catteries now advertise their testing protocols as a mark of quality. Kitten buyers increasingly research genetic health before purchasing, and breeders who test their cats demonstrate a commitment to producing healthy kittens.
Common Genetic Conditions in Cats
Different breeds carry different genetic risks. Here are the most significant conditions that DNA testing can identify:
Hypertrophic Cardiomyopathy (HCM)
HCM is the most common heart disease in cats, causing the heart muscle to thicken and function less efficiently. Genetic mutations have been identified in Maine Coons and Ragdolls, though the condition affects many breeds.
| Breed | Mutation | Inheritance Pattern |
|---|---|---|
| Maine Coon | MyBPC3-A31P | Autosomal dominant |
| Ragdoll | MyBPC3-R820W | Autosomal dominant |
Important: A negative DNA test for HCM doesn’t guarantee the cat won’t develop heart disease. Non-genetic forms exist. Maine Coon and Ragdoll breeders should continue annual cardiac ultrasounds regardless of DNA results.
Polycystic Kidney Disease (PKD)
PKD causes fluid-filled cysts to form in the kidneys, eventually leading to kidney failure. The condition is most prevalent in Persians and Persian-derived breeds (Himalayan, Exotic Shorthair, British Shorthair, Scottish Fold). The PKD1 mutation has autosomal dominant inheritance—affected cats have at least one copy of the mutation.
Progressive Retinal Atrophy (PRA)
PRA causes progressive blindness as photoreceptor cells in the retina degenerate. Several forms exist:
- PRA-b (Bengal cats): Recessive inheritance; causes blindness typically by 2 years of age
- PRA-pd (Persian/Persian-derived): Recessive inheritance
- PRA (Abyssinian/Somali): Recessive inheritance
Pyruvate Kinase Deficiency (PK Deficiency)
PK Deficiency affects red blood cells, causing intermittent anemia. It’s found primarily in Abyssinians, Somalis, and domestic shorthairs. The condition is recessive—carriers are healthy, but breeding two carriers produces affected kittens with shortened lifespans.
Spinal Muscular Atrophy (SMA)
Maine Coons carry risk for SMA, a recessive condition causing progressive muscle weakness and wasting due to loss of spinal cord neurons. Affected kittens show symptoms by 3-4 months of age.
Other Breed-Specific Conditions
| Condition | Breeds Affected | Inheritance |
|---|---|---|
| Glycogen Storage Disease IV | Norwegian Forest Cat | Recessive |
| Gangliosidosis (GM1/GM2) | Siamese, Korat, Burmese | Recessive |
| Myotonia Congenita | Devon Rex | Recessive |
| Hypokalemic Polymyopathy | Burmese | Recessive |
When to Test Your Cat
DNA testing can be done at any age—the genetic code remains constant throughout life. However, strategic timing maximizes the value of testing:
Request DNA test results from the breeder before buying a kitten you intend to breed. Or arrange to test the kitten before finalizing the purchase.
Test any cat entering your breeding program before their first mating. Results take 2-4 weeks, so plan ahead.
Know your queen’s genetic status before evaluating potential studs. You’ll need to verify any carrier statuses are compatible.
Test new additions before integrating them into your breeding program, even if coming from a reputable cattery.

How to Choose the Right Test
Match Testing to Your Breed
Different breeds require different tests. A Persian needs PKD screening; a Maine Coon needs HCM and SMA testing; a Bengal needs PRA-b. Start by identifying your breed’s known genetic conditions through your breed club or registry, then select a provider that covers those specific tests.
Consider Registry Requirements
If you’re registering cats with TICA, their recognized tests (Optimal Selection, MyCatDNA) streamline documentation. CFA breeders benefit from the Neogen partnership. UC Davis results are universally respected for their scientific credibility.
Budget vs. Comprehensiveness
If budget is a concern, the CFA DNA Test at $70 offers exceptional value with 120+ tests. For comprehensive genetic diversity data and advanced breeding tools, Optimal Selection’s higher price delivers additional functionality. Individual tests from UC Davis work well if you only need specific screening.
Turnaround Time
Most providers deliver results in 2-4 weeks. If your queen is coming into heat soon, factor turnaround time into your planning. Order tests early to avoid delays in breeding decisions.
Understanding Your Results
DNA test results categorize your cat’s status for each tested condition:
| Result | Meaning | Breeding Guidance |
|---|---|---|
| Normal/Clear (N/N) | No copies of the mutation | Can breed to any partner for this condition |
| Carrier (N/M) | One copy of the mutation | Breed only to clear cats; 50% of kittens will be carriers |
| Affected (M/M) | Two copies of the mutation | Generally should not breed; all kittens will be carriers minimum |
Dominant Conditions (HCM, PKD)
For dominant conditions like HCM in Maine Coons or PKD in Persians, even one copy of the mutation (N/M) means the cat is at risk of developing the condition and should not be bred. All offspring would have at least a 50% chance of inheriting the mutation.
Making Breeding Decisions
- Never breed two carriers of the same recessive condition together
- Carriers can be bred to clear cats—resulting kittens will be healthy (though 50% carriers)
- Exclude cats positive for dominant diseases (HCM, PKD) from breeding programs
- Verify blood type compatibility for Type B females bred to Type A males
- Document all results and share transparently with kitten buyers
Frequently Asked Questions
Comprehensive cat DNA panels range from $70-$190 depending on the provider. The CFA DNA Test (Neogen) at $70 is the most affordable comprehensive option. Individual tests from UC Davis start around $40-$85. Bulk discounts are available from most providers when testing multiple cats.
It depends on your breed. For Maine Coons, HCM and SMA testing are essential. For Persians and related breeds, PKD testing is critical. For Abyssinians and Somalis, PK Deficiency and PRA testing are priorities. Blood type testing is important for all breeds to prevent Neonatal Isoerythrolysis.
Neonatal Isoerythrolysis (NI) occurs when Type B queens are bred to Type A toms, producing Type A kittens. The queen’s colostrum contains antibodies that destroy the kittens’ red blood cells. Prevent it by DNA testing for blood type and avoiding Type B x Type A pairings, or by removing kittens from the queen for the first 16-24 hours if the pairing can’t be avoided.
For recessive conditions, yes—but only to clear cats. The kittens will be healthy (50% carriers, 50% clear). For dominant conditions like HCM or PKD, carriers/affected cats should not be bred, as they can pass the disease to offspring even when bred to clear cats.
TICA recognizes Optimal Selection and MyCatDNA for DNA profiling, both using the ISAG 2020 standard. CFA has an official partnership with Neogen, offering the CFA DNA Test with member discounts. UC Davis VGL results are widely respected across all registries for their scientific validation.
No. DNA tests only detect known genetic mutations. HCM can also develop from non-genetic causes or mutations not yet identified. Responsible Maine Coon and Ragdoll breeders continue regular cardiac ultrasounds (echocardiograms) even with negative DNA results. DNA testing reduces but doesn’t eliminate risk.
Most providers return results in 2-4 weeks from sample receipt. Orivet guarantees a 28-day turnaround. Plan ahead—test well before your queen’s expected heat cycle so you have results in hand when making breeding decisions.
