We love cats as much as anybody, but deep down we've never really trusted them. Based on this supercut of naughty felines taken from the Animal Planet show 'My Cat From Hell,' it seems we were right all along.

These cats hiss menacingly, scratch and bite their owners and other cats repeatedly. One woman fights with a growling kitty for a plastic bag of Quinoa. Who knew kitties were willing to maim for cereal? And another tries to pet a grumpy cat and gets a handful of fur and sharp teeth for her trouble.

Without a doubt, all of the cats in this video have seriously bad attitudes. It's enough to turn you into a dog person, for sure. Still, none of these kitties seem as downright demonic as this hellcat.
