my cat has FIV. he is 2 years old and we found him one day outside. I've heard that sometimes it doesn't even affect the cat, but I want to hear from someone who's had a cat or had a cat with FIV. did you cat show symptoms? did it pass early on? what should I do exactly to keep him healthy, meaning, what are the best medicines or supplements you guys have used to keep your kitty in check?
