We had a cat called Monster once.

He/she had both set of genitalia, but we referred to him as 'he' before we knew. He was black except for a white spot on his chest, and so fat he laid on his back he was almost the size of a small dog. However he would only lay in places he knew people would pass by in. He'd stare you down before trying to claw your ankels, so his claws would get caught in your pants and you'd drag him down the hallway.
He would also hid under beds and try to get your feet from there as well.
And closets too.

He was just a very upset kitty.
