Continuity: When Odie comes out on the porch to keep Garfield company, his collar and tags are visible; even more so when he attempts to get back in. But when the shot pulls away to show Odie alone on the steps (before running off after the scooter), his collar is gone. Part of the plot hinges on Jon trying to find Odie, who wasn't wearing his tags.

Revealing: When one of the men picks up Garfield from his cage to display to potential buyers at the pound, you can see the man's right hand "entangled" with the computer-generated Garfield.

Continuity: When Garfield is looking for Telegraph Tower, he says it's next to a blue and orange tree. On the Kibbly Kat box however, there is no blue and orange tree on the box, let alone next to the tower.
