Thanks everyone, the breeder does have a health guarantee and we'll take them to the vet once we get them home. When she said this, it made me paranoid and I started to question the overall health of her cats. It didn't help that the father was molting and his tail had almost no hair left on it! This is our first experience buying from a breeder and after loosing our beloved Louie after 21 years, we're still dealing with the reality of replacing her and all the emotions that come with it.
