Leave it to a dog to keep a cat on its toes.

In this case, the pooch got a trio of cats way off its toes when he snuck up behind the felines and scared the holy heck out of them while they watched a bird outside the front door.

The dog is clearly getting a jump on the Halloween season with some ghoulishly frightening practical jokes. That, or he wants everyone to know canines are the best pranksters in the animal kingdom and that the rivalry with cats is still as fierce as ever.

You could watch all the Saw movies back-to-back and you'd still have a hard time being as terrified as these poor kitties are.
