I had always thought that FIV was only contagious through deep bite wounds, that the saliva had to get deep into a cat's system for them to be infected. Everyone I had talked to said this. But I was recently talking to a lady who works at an FIV sanctuary, She told me that FIV can be spread through saliva, so the cat has to be isolated from FIV - cats. i have a cat who is FIV but there's no way to separate her from the others. Has anyone heard anything about this? Does anyone know if FIV is contagious through saliva?
