John and Catherine Michaels' quiet neighborhood is being stalked by cat burglars. Alarmed that their humans are not concerned about being robbed, Phoebe and Boomer, the couple's cats, decide to take matters into their own paws.

To protect their humans' valuables, the felines become cat burglars themselves, "stealing" their masters' jewelry and hiding it until the real cat burglars are caught.

Phoebe and Boomer embark on their daring escapade, despite the presence of the other family pet, a German shepherd puppy named Gus, who thinks he's a police dog. Unfortunately, Gus is way too cute, friendly, and naïve to protect the house from any intruders.

Phoebe and Boomer are confident that they have saved the day, until some unfortunate events occur that throw their plan into a tailspin, and end in a way they never, ever imagined.
