Cat AIDS is a illness that cats get from unprotected sex. Contraseption will prevent Cat AIDS but this is not available to all cats out there. Cat Contraseption should be sold in all pet stores as Chris, Mary and the rest of the Cat AIDS awarness group point out.
Cats can also get Cat AIDS from sharing needles and from open wounds, however, sex is the most common. Each pet owner should talk to their cat about sex and if the cat has sex before the age of 17 (Cat years), they should be turned into the police.
