T3000 is a green robotic dog catcher who was built to replace Al and Pete. It's job is to catch strays and pets who are wanted for various crimes. It was very strict, catching any pet who had ever done anything wrong. It was stopped by Garfield, Odie, Al and Pete. Garfield changed the robot into an ice-cream vendor, but it promised to come back.
- It is a parody of the T9000 from Terminator, including a voice similar to Arnold Schwarzenegger.
