I have a neutered male cat who’s about 20 months old. He loves doing what the Americans call ‘biscuits’ (I don’t think there’s a British English word for it). He does it two or three times a day and will happily perform it on any family member. While he’s biscuiting, he often moves the lower half of his body onto its side, revealing an erect, cactus-like penis. It’s not a problem (he’s neutered and there’s no ejaculate) but I was wondering just what is going on here? Why would doing an action that is the instinctive action a kitten performs to get milk from its mother cause this apparent sexual arousal? It all seems a bit Oedipal. Any insights are welcome.
