The Hall of Horrors is open. Step into the nightmare!

Mickey is put in charge of his vacationing neighbors' cat, Bella. His best friend Amanda comes along to help out. All they have to do is make sure Bella has enough to eat and doesn't destroy the furniture. Seems simple enough. But Bella escapes from the house and is hit by a car. Mickey feels awful. What is he going to do? Amanda has an idea to replace the cat with a look-alike from the local pet store, Cat Heaven. They find a cat that looks exactly like Bella, but the clerk won't sell it to them, so they decide to steal it. Big mistake! These cats are more than they seem to be.
