Ok, here is what you do. As soon as you pick kitty up, put him inna kitty-carrier, or wrap him in a towel. Take him to the vet immediately. Get kitty all his shots and tested for rabbies, FIV, lukemia and such. After handling kitty, wash your hands. If you cant take kitty to the vet immediately, keep kitty in a cat-carrier and keep him separated from your other animals. Always wash you hands after handling.
