I have 5 FIV+ cats and they are extremely healthy and active, and they live alongside both very young and very old non-FIV cats. You would only have to worry if your cat was extremely aggresive, which I very much doubt. Calling FIV "Feline AIDS" really puts the wind up people unnecessarily. Cats with FIV do not get cancer any more easily than any other cat, nor do they get other disorders such as renal failure any more easily. They need to go to the vet for quick treatment if they come down with any kind of infection or get a wound so they can be started on antibiotics right away, and the course of treatment is usually longer. They can get sore gums and fragile teeth more easily. That's it.

Here's a very useful website:

Maximus is very beautiful and looks a lot like my Cattulus - hmm! two tabbies with Latin names.
