I know we all have different opinions/outlooks, so I'm not trying to tell anyone what to think. But I really don't understand why this is bothering you.I think it’s been longer than that. He was neutered mid-April. I think he’s forever a bed humper
If he was humping many things and/or humans' legs I would understand wanting to at least try discouraging it. But since it is just his bed, and while just getting comfortable, I don't see what is wrong.
It's likely it has nothing to do with sexual urges any more, and maybe became a fixed behavior from back when it actually was about sexual urges, but now is just associated with comfort/relaxation.
My cat still humps at age 10, but quite rarely (at least I see him do it only rarely). It's also right between kneading and getting settled in for a nap.
My cat does have a behavior I think is gross, which is scooting on the living room carpet after pooping. I started a thread on it, but haven't resolved it yet. I'd take humping over carpet-scootong any day.
Is there ANY way to stop carpet scooting?
