Years ago, I attended a cat show and observed two males doing the deed with each other. I asked the owner about that; she said that it’s a common phenomenon among young cats, but that they eventually grow out of it.
Poor Pepper...abandoned for another penguin. I guess he will have to find another mate now.
I’ve seen a lot. Animals do a lot of things. I’ve never been one to find the argument convincing that because a behavior is observed in animals that it is validated or a good behavior for humans. I’ve seen a dog humping a cat. I also observed what is more often the case which is smaller males being forcibly raped. Great apes same sex coupling is almost always tied to suppressing and forcing submission. I’ve never seen cats involved in gay sex, if it does happen it is probably not very common though is probably more likely in cases where the animals have no access to females.
