It’s officially “be cruel to your animals” day. While human kids everywhere are getting excited about being witches, goblins, and Hannah Montana, pets dread even the thought of what their masters will force them to endure tonight. But we’re glad for this one day a year when we can be borderline abusive, because it gives us hilarious pictures like this.

Our own kitties may be spared tonight. MAY be. It depends on how much time we want to spend looking through our basement for old doll clothes. So Buster and Bijou, if you’re reading this, here’s a fair warning: go hide the cabbage patch dolls NOW. You might want to get rid of all the toilet paper in the house, too. Unless you really want to play a game of Let’s Make a Mummy.

After the jump, there are 29 more pictures of hilarious pet costume cruelty… (picture thanks via email forward)
