Why is my cat acting strange, humping, and biting me when I lie down?

Updated On September 23rd, 2025

Pet's info: Cat | Ragdoll | Male | 14 lbs

My cat is behaving strangely. He jumps up on my belly when I'm laying down and first he marches and purrs and then he starts wiggling his butt in a very strange way and tries to bite me if I try to get him off. What is wrong with him??

This may actually be normal affectionate behavior for a cat (kneading/‘making muffins’ and wanting to be stroked along the length of his back and tail) If he is not neutered and is between 6 months-a year old and only recently started acting like this, hitting puberty may partially explain the change in behavior. Non -prescription over the counter pheromones such as Feliway plug ins or sprays or a Feliway collar or daily VetriScience liquid Composure supplements may help calm him down/reduce his biting tendency, as may having him neutered by your veterinarian. Good luck!
