Wow, this is what happens when you try to interpret animal actions by human standards. The cat is trying to mate with the female.  If you really want to interpret this by human standards then the right way to go is to call the cat a dumb SOB becuase he’s trying to mate with a dead cat. If you are like me then you just accept the fact that cats are not humans therefore they can’t think like we do. PS: My cat did the same thing all the time with a wool jacket my mom had. He would ‘cardiac massage’ it and bite on it. Oh, and he also used to have a boner while he was doing it.
