A positive testing of FIV for your cat is not a sudden declaration of death and doom.  Although FIV and HIV are similar; FIV is a distinctly species specific diseases.  Contrary to popular belief FIV is not easily transmitted between cats.  A deep cut or bite is most often the culprit while sexual activity is normally not a risk although all FIV positive cats should be spayed or neutered.  And let’s be honest, you should really be spaying and neutering your cats anyway, cuz clearly Bob Barker thinks you’re all jackasses – and he’s right.

From the Cornell University College of Veterinary Medicine:

It has been estimated that the majority of FIV+ cats never become ill from the virus. From what we have seen, FIV+ cats are more likely to lose their lives because they have tested positive (and no one is willing or able to take them), than because they actually become ill.

From The Best Friends Organization:


FIV FACTS

1. The Feline Immuno-deficiency Virus is a slow virus that affects a cat's immune system over a period of years.

2. FIV is a cat-only disease and cannot be spread to humans or other non-felines.

3. FIV cats most often live long, healthy, and relatively normal lives with no symptoms at all.

4. FIV is not easily passed between cats. It cannot be spread casually - like in litter boxes, water and food bowls, or when snuggling and playing. It is rarely spread from a mother to her kittens.

5. The virus can be spread through blood transfusions, badly infected gums, or serious, penetrating bite wounds. (Bite wounds of this kind are extremely rare, except in free-roaming, unneutered tomcats.)

6. A neutered cat, in a home, is extremely unlikely to infect other cats, if properly introduced.

7. Many vets are not educated about FIV since the virus was only discovered 15 years ago.

8. FIV-positive cats should be kept as healthy as possible. Keep them indoors and free from stress, feed them a high-quality diet, keep and treat any secondary problems as soon as they arise.

It would seem the preferable choice would be to house FIV positive cats with other positives, or a one cat household.  However there are success stories of FIV positive cats living with normal cats and never passing on the virus.

Here is an example of one very handsome and distinguished gentleman named Grayson:



This handsome cat with a distinguished name has impeccable cat manners and a wonderful disposition. Grayson was a stray who was unclaimed at the shelter. He is doing well in our adoption center, and is warm, safe, and has plenty to eat. The only thing he's missing is the thing he's never known--a permanent home. He is about 2 years old, very calm, mellow and extremely friendly. Grayson is FIV positive, so needs to be in a single cat home, or with other FIV cats. He is very patient and does well with children. Call (831) 333-0722 if you are interested in adopting this distinguished boy.
