Some cats have a little “sweet” spot at the base of their tail that they love to have scratched or thumped. You might call it the cat’s “g-spot.” Judging from their behavior, I’d say that it stimulates the pleasure center in their brain. Whether the feeling is sexual or not is anyone’s guess. It’s hard to figure out what another human being is thinking, let alone a creature of another species, especially one that seems to display an array of baffling behaviors the way cats do.
Do cat lovers have an opinion about this subject? One friend assures me that the feline enjoyment of spanking is very much related to sex. That’s what her vet told her, she says. Besides, she once noticed that Carlton, her cat, had “a huge erection” from getting thumped on the rump (or “tom-tomming,” as my friend calls it). Carlton is very demanding about getting tom-tommed. He insists on it daily, regularly, several times a day—well, almost around the clock. Gets downright ornery if he doesn't get a piece of action, so to speak.
Suffice it to say that Carlton goes nuts when tom-tommed. And it doesn't seem to matter whether the cat has nuts or not. Carlton has been neutered. Mittens, my cat on loan, is female as well as being spayed. So neither gender nor whether the cat has been spayed or neutered makes any difference.
I’m not sure why male cats would find butt-whacking (or tom-tomming, or whatever you might call it) so pleasurable. With female cats, I can sort of see why they might have an instinctual predilection for pelvic presentations. It’s what females in heat do. For instance, the posture Mittens assumes is exactly that of a receptive cat waiting to be mounted. The difference is that although her tail is raised high, she doesn’t hold it to the side of the body (which is what the female does to accommodate entry by the male cat’s penis). She also doesn’t tread rhythmically with her rear legs. (I suppose I can be thankful for that.)
Enough about g-spots and cats’ mating behavior. I’m not trying to turn this into a kitty porn site!
Just for good measure, here’s another video of a cat getting spanked. No doubt about it -- cats are strange creatures.
