I just know cats can have AIDS too. I read it from a poster at the animal hospital when I take Charlie to see a vet. There is HIV for human and there is FIV (Feline immunodeficiency virus) for cats. There is about 10% of cats in North America are FIV infected FIV. Cats of FIV basically suffers the problem like human with HIV. Its immune system will stop working and it eventually dies from all sorts of diseases.
Condom can stop the spreading of HIV in human, maybe I should invent condom for cats, so the cats can have safe sex without the danger of having FIV. Then I did a little bit more research and it turns out FIV is transmitted by cat saliva, so my cat condom idea is not that useful. Or maybe I have to make a condom that’s is big enough for cat’s head.
