Just when you thought grumpy was mean

Introducing...Demon Cat!

Almost a gremlin

This cat look like it will slash your tires pour bleach on your clothes kill your dog and still be angry enough to want to beat the mess out of you once you get home.

looks like the inner alien from "Independence Day."

The mother of Hades was Rhea, and she was supposed to be kind, so yeah, I guess she was sweet.
