Abandoning animals messes with your head

These creepy ads from Portugal warn of the dangers of mistreating animals. (See larger versions here.) "When you abandon a dog, you never leave it behind," says the ad on the left. Plus, you’ll have painful, dog-shaped tumors suddenly appear along the top of your head. Same with cats, apparently. The lesson here is clear: If you’re going to abandon a pet, you’ll need a good hat. And decent health insurance, in case those things pull a Medusa on you and burst out of your head.
