Animation errors are phenomena in cartoons, when certain scenes look strange, inconsistent or sometimes illogical. Usually these mistakes are committed by artists working on animation, often due to lack of diligence.

Sizing and shape errors
These errors usually occur as attempts of depicting certain facial expressions of characters, especially verbal communication (talking, yelling, yawning and so on). Female cats in Garfield and Friends episodes often suffer from these imperfections.
The episode's goofs are intentionally full of weird and inconsistent scenes, since its humor is supposed to revolve around the lack of logical continuity.
