Monday Mystery: Solve the Riddle

I have a new riddle for you today! I think this one might be a little bit hard, but you will probably get it if you do your best thinking.

What has a head like a cat, a tail like a cat, and four legs like a cat, but isn't a cat?

You may commence your thinking now!

Again, you might think the answer is Harley, because I am not certain he is a real cat. But if that is your guess, you would be wrong.
