About National Cat DNA Day
National Cat DNA Day takes place on Saturday, 19 September 2026. The day celebrates the science of feline genetics and encourages cat owners to learn more about their pet’s breed mix, health risks and unique traits. It was created in 2020 by Basepaws, a feline genetics company that produced the first at-home comprehensive cat DNA test.
How to Celebrate National Cat DNA Day
This is a day built around curiosity, so the best way to mark it is to find out something new about your cat. Here are several ways to take part:
- Order a cat DNA test – Companies such as Basepaws and Wisdom Panel offer at-home kits that use a simple cheek swab or fur sample to reveal breed groups, traits and health markers. The results usually arrive a few weeks later.
- Read your cat’s report together – If you have already tested your cat, dig the results back out. Reviewing breed percentages and trait predictions is a fun way to understand quirks you may have always wondered about.
- Learn about feline breeds – Spend time reading about the breed groups your cat is most similar to, whether that is Western, Eastern, Persian or Exotic, and compare the typical personalities and coat types.
- Book a wellness check – DNA results often flag predispositions to conditions like polycystic kidney disease or hypertrophic cardiomyopathy. Use the day as a prompt to schedule a routine veterinary visit.
- Support feline research – Feline genetics has historically been under-funded compared with canine and human research. Donating to or sharing the work of feline genetic studies helps close that gap.
- Share your cat’s story – Post your cat’s breed results, photos and surprising health facts on social media to spark interest among other owners.
- Donate to a shelter – Many rescue cats have unknown backgrounds. Giving food, blankets or toys to a local shelter is a fitting way to honour cats whose genetics are a mystery.
- Adopt or foster – If you have been considering adding a cat to your home, a day centred on celebrating cats is a good moment to visit a rescue and meet cats in need of a family.
What is National Cat DNA Day?
National Cat DNA Day is an annual observance dedicated to feline genetics and the growing field of cat science. It encourages owners to explore what their cat’s DNA can reveal, from breed ancestry to inherited health risks and physical traits. The day is aimed at cat lovers, pet owners and anyone curious about the biology behind their feline companions. At its heart, it is a celebration of how much we can now learn about cats that was a mystery only a decade ago.
When is National Cat DNA Day?
National Cat DNA Day is observed every year on 19 September. In 2026 it falls on a Saturday. The date carries a playful symbolism: September is the ninth month, a nod to the old belief that cats have nine lives, while the 19th echoes the 19 pairs of chromosomes found in the domestic cat’s genome. Because the date is fixed, it always lands on 19 September regardless of the year.
The History of National Cat DNA Day
National Cat DNA Day was launched in 2020 by Basepaws, a petcare genetics company founded in 2017. Basepaws built its reputation by creating what it describes as the world’s first at-home comprehensive cat DNA test, often compared to a “23andMe for cats”. The company wanted a dedicated day to raise awareness of feline genetics and to highlight the achievements of a field that has long sat in the shadow of dog and human research.
The science behind the day is genuinely remarkable. The domestic cat genome is roughly 2.7 billion bases long, and cats share around 99 per cent of their DNA sequence with one another. The small differences that remain explain coat colour, body shape, behaviour and susceptibility to certain diseases. By analysing these variations, companies can offer owners a detailed picture of their cat’s ancestry and health.
Cat domestication stretches back more than 12,000 years to the Middle East, yet serious genetic study of cats is a far more recent development. National Cat DNA Day was created to celebrate that progress and to encourage more people to engage with feline science. If you enjoy marking days that celebrate cats, you might also like World Cat Month, observed throughout October.
Fun Facts About National Cat DNA Day
- The domestic cat has 19 pairs of chromosomes: 18 pairs of autosomes and one pair of sex chromosomes.
- The feline genetic code is approximately 2.7 billion bases long.
- Cats cannot taste sweetness, a quirk written into their DNA that makes them unusual among mammals.
- Modern cat DNA tests can screen for dozens of genetic health markers, including polycystic kidney disease and hypertrophic cardiomyopathy.
- Breed reports often group cats into Western, Eastern, Persian and Exotic categories rather than single breeds, reflecting how mixed most pet cats are.
- Basepaws, the company behind the day, was founded in 2017 and launched the observance in 2020.
Why National Cat DNA Day Matters
Beyond the novelty of discovering your cat’s breed mix, National Cat DNA Day serves a practical purpose. Genetic testing can flag inherited health conditions early, giving owners and vets the chance to monitor or manage them before they become serious. The day also champions a research field that remains under-funded, helping to build the knowledge base that improves feline welfare for all cats.
