Onyx is Stella's sister and littermate. She's our crazy one. She likes to hides in things- pots, boxes, cupboards, anywhere she can fit, really. She's an EXTREME lover. You can't really play with her with just your hand because right when you touch her she collapses over purring. She also announces herself everytime she runs through the cat door. Sometimes she will randomly call for you in the house, and you call her name and she will answer back and forth until she runs in and finds you. I've had her since she was a babe.
