Sometimes when you pet your cat she seems to enjoy the affection – she purrs, she stretches, maybe even gives a contented little meow. But in an instant, it's as if a flip gets switched and the predator within her pounces out! All of a sudden she latches on to your hand and chomps down on you with her teeth…hard. She may even wrap her paws around your hand and “bunny kick” your arm with her back feet, raking her hind claws against your skin. Ouch! How can a cat be so sweet one minute and such a ferocious ball of fury the next? You’ve fallen victim to what’s known as petting aggression, my friend.
