DNA testing is a great way to learn more about your pet. This is something that is always rewarding. It helps you make decisions about your cat or dog and helps you understand your pet better.

In the past, the only way to learn about pets, including domestic cats, was to live with your feline companion. Your options were especially limited if your cat was a rescue and you knew little about his or her ancestry and breed. Assessing your pet’s DNA wasn’t a common practice among pet owners, but that’s recently changed.

Nowadays, cat owners have the option of testing their pet’s DNA. The information gleaned from a cat DNA test can help you make important decisions for your pet, from what to feed him or her to whether or not to adopt another pet.

What can you learn from your cat’s DNA?

Cat Breed Personality and Temperament

Do different cat breeds have different personalities?

It certainly seems as if they do. Some breeds are infamously linked to their personality traits.

DNA influences the majority of traits your cat has, including his or her temperament and personality.

  • Does your cat like to be held?
  • Is your cat skittish or “talkative” or demanding?
  • Does he have a tendency to gain weight easily?

Most of these traits are linked to your cat’s breed. Some breeds are friendlier than others. Some standoffish, others aggressive. And while there are individual cats who don’t fit the norm for their breed, in general, you can expect your cat to behave a certain way based on his or her breed.

Ancestral Roots

Just as you would take a DNA test to learn more about your family tree, you can get similar information by testing your cat’s DNA. Also like you, your cat inherited half of its DNA from its mother and a half from its father. Each of them received half from each of their parents, so your cat has a quarter of the DNA from each grandparent.

How much of the traits that pass on to your cat varies from case to case. For example, your cat might be ¼ Siamese, but not behave or look much like a standard Siamese. On the other hand, a different cat that is also ¼ Siamese might look very much like the breed and/or act like it. Though DNA offers a great deal of insight into your cat’s heritage and what you can expect, it’s still difficult to predict exactly how much that DNA will affect your cat.

Look at it this way: DNA can explain why your cat acts or looks a certain way, but it might be more difficult to predict whether your cat will act a certain way. You might say “Fluffy is talkative because she’s part Siamese,” but it would be more difficult to say “My kitten Fluffy will be talkative because she’s part Siamese.” That might ultimately be the case, but it’s not a guarantee.


One of the most common reasons people take DNA tests is to learn about their potential for inherited health risks. Our genes offer insight into our health and they do the same for cats. To date, veterinarians have identified more than 250 genetic diseases in cats.

Understanding your cat’s genetic risks can help you make many important decisions for your pet. You can use DNA test results to plan a proactive approach to your cat’s healthcare. DNA risks can help you make decisions about your cat’s diet, vaccinations, fitness routine, and overall lifestyle. It can also help you identify when something is a problem instead of just being part of his or her breed’s makeup.

Understanding the health risks a particular breed faces can even help you when choosing a cat breed. If you know you’d be capable of caring for a cat with a high-risk for a particular genetic disorder or that it would be too difficult to handle, you can use the information to determine which breed would be right for you.

Is Cat DNA Testing Worth the Investment?

Some might view the investment in a cat DNA test as a luxury. DNA tests for pets cost around $100 and aren’t a necessary part of caring for your pet. On the other hand, they are an investment that can help you learn a great deal about your cat. This is especially true if your cat is a rescue and you know very little about them.

A few cat DNA test kit options are available, including a kit from that is available for $95. With Basepaws, you get a general report that provides insight into your cat’s personality, ancestry, and genetic health risks. It’s enough to satisfy your curiosity and help you make proactive decisions about your cat’s health.

Learning more about your cat’s DNA is a great way to form a lasting bond with your pet. Cat breed personality is a major indicator of why certain cats act a certain way. DNA test results provide information about why your cat is the way they are. Identifying the genes of different breeds in your cat is a great way to learn more and better understand your pet.
