Genetic tests are available for cats. A quick swab of the inside of a cat's cheek can the reveal breed ancestry encoded in the pet's DNA.
A DNA test for a cat first reveals the likely region of origin for the cat's ancestors. Then, genetic markers consistent with individual breeds are identified. The test is most effective on cats born in the U.S. since past research has created a larger data pool.
Genetic testing of cats is usually to satisfy curiosity. However, DNA testing may have practical applications. Understanding a cat's heritage may help a veterinarian to make the correct diagnosis, as certain disorders are more prevalent in some breeds.
