Everyone knows that certain things just don’t go together. Like toothpaste and orange juice – and cats and dogs. And despite assurances from some pet owners that their mutt and kitty get on perfectly well, we’re not so sure.

Still, whether you’re a cat person or a dog person, we hope you enjoy this collection of kitties and pooches beating the crap out of each other.
