Yes, "Basepaws" is a legitimate company. It is a genetic testing service that analyzes the DNA of cats for traits, ancestry, and disease risks. The company was founded in 2016 by Anna Skaya. They offer a detailed look at a cat's breed makeup and likely traits. They also provide health testing that lets you know if your cat may become ill or if they have a predisposition to a certain health condition. However, it's always a good idea to do your own research and check reviews before making a purchase.
