S1·E9 A Game of Cat and Mouse

Squeak and his family move in to Jon's house while Jon and Odie are out. Garfield allows Squeak's family to remain in the house on the condition that they be his servants. Jon comes back and Garfield has to remove Squeak and his family before Jon called Rat-Tator Pest, who's hefty bill would have meant that Jon would not be able to afford lasagna for years.
