If your cat locked you out of the car as soon as you stepped out, that could mean something. It can also choose to wake you up every morning with its claws. Whatever our pets demand of us, you can see their attitude in their actions, or even in their eyes.

We at Bright Side adore these smart little creatures and are sharing 18 pics that show how mean and nasty they can sometimes be.
