Jessica's Cat Trick (Sweet Valley Kids #5)

One afternoon identical twins Jessica and Elizabeth Wakefield are playing outside when they find a cat that has no home. Cats aren't allowed inside the Wakefield house because Mr. Wakefield and Steven have allergies. But more than anything the twins want a cat of their own. They even think of a perfect name for her--Misty. Wouldn't it be OK to keep Misty for just a little while?
