Does/did your dog mount your cat/kitten?

It occurred to me that Buddy will try to hump the puddy cat when I get him/her, since he does this with all his doggy friends (if they let him get away with it, that is). I know it's his dominance behaviour thing, and the only thing that seems to stop it is if the other animal tells him no.

Just wondering what your experiences have been in this regard.
