Something I have learned in my short time as a cat owner is that, as Sandie points out, just because someone hangs out their shingle as a breeder, that doesn't always mean they know what they're doing. Next time, educate yourself so that you can ask good questions about your cat's bloodline. If the breeder is reputable, they should be willing to answer your questions clearly. Hopefully, that will up your luck with the longevity of your next kitty.
