I have a male toy poodle and one of my cats is female. All are neutered. They all get along well and often sleep on the couch together. Tonight, I caught my poodle humping my female cat. My cat is about 4 pounds heavier than my poodle, but didn't try to stop him, although she looked a bit upset. My poodle didn't look like he thought he did anything wrong, and my cat wasn't hurt, so I didn't scold him. Has this happened to anyone else's pets and is it normal?
