Garfield isn't a mauser. He doesn't even mind mice - as long as they don't get in his way, he couldn't care less. But when his mouse friend Squeek invites his big family to stay at Jon's, they quickly take over the entire house-turning the kitchen into a Mouse Paradise complete with tennis court, spa, and buffet. Jon gives Garfield an ultimatum: get rid of the mice, or Jon will call an exterminator.
