Ah, we love it when cats fight back! (Unless it's us they're fighting, obviously.)
Just look what happens when a couple of curious pooches start sniffing around the cardboard box where the family cat just happens to be hanging out. Don't be fooled by that cute little face: this fired-up feline gives as good as she gets.
And if you're in the mood to watch some more sneaky cat attacks, we think we have something that will interest you right here...
