WHY THIS DAY MATTERS

Why National Cat DNA Day is Important

Genetic research will benefit all cats

Through collecting data from cat's genomes, researchers can work better understand the mechanism of genetic diseases in cats, as well as explore ways to minimize inherited disorders and have advancements in breeding practices. The end goal is for all cats around the world to live healthier lives and thanks to National Cat DNA Day and its supporters, this dream is closer than ever to becoming a reality!

Cat DNA testing can help locate lost cats

Cat DNA tests have the ability to be conducted noninvasively and reveal a cat's unique genetic traits and pedigree. This information can provide valuable insight into ownership of a cat and could prove extremely useful in returning lost cats home or helping to identify them should they become stolen.

DNA tests can pinpoint genetic diseases

With advances in genetics, cat owners can now utilize DNA tests to determine if their cats carry certain genetic traits that may put them at risk for developing genetic diseases. This means pet owners can properly identify an issue early on and take steps to ensure the best possible care for their furry friend!
