Oh, parvi is a bad desease ! I have two cats that have been infected with parvi before their birth. The have both ataxia but are the loveliest cats in the world, loving their lives and are happy.The black one is Tali my girl and the tan one is Sparky and he is my special boy. He is a bit off in the head due to having parvi before his eyes where even open yet. But he is a good dog. Tali is his therapy dog lol.
