Good for you. You gave this kitty something he needs and he can give you what you need. You just don't know it yet. I had a Feline Aids Kitty. We had him for 9 years before he passed/ He also more than likely gave his virus to his housemate, another kitty. As long as they stay indoors they can go on to live perfectly normal lives. They do get sick a little more often but nothing a course of antibiotics can't fix.

Cats are very affectionate. They make good listeners and have such personality. They don't play to much or need walking. They are good with sleep. Good thing because I love to sleep. I hope this continues to work well for you.
