kinky
Our 4-year-old neutered male FIV+ cat has taken to nursing from the teats of our 11-year-old neutered male cat. They both seem to be enjoying it -- there's a lot of purring and languid mutual grooming going on -- so I don't see any reason to stop them. The younger one used to do this when he was a kitten, and then they stopped for a few years. But lately they're been doing it again, and doing it a lot : every time I walk into the living room, there they are with the kneading and the suckling noises. It's the teensiest bit disturbing, you know?
