Choose your cat: a black cat strutting along with a kitchen knife clamped in its mouth, a smug gray tabby sticking its tongue out, or a wide-eyed black cat curled over a swirl of blue. Each one has attitude, and each one makes people ask about your keys.

The black cat with the knife dangles on a little chain from a split ring, and the gray tabby and the blue swirl cat ride swivel clasps. The tabby even has a striped tail that swings on its own. Clip yours to your keys, a backpack, a purse strap or a work lanyard. It is a quick laugh for the cat lover who has everything, a stocking stuffer for teens, and a fun extra tucked into a birthday card. Pick two and split the pair with your best friend.
