Fat cats are usually Plucky Comic Relief characters, though the occasional fat cat with an important role does come along some times. If there's a Crazy Cat Lady around who actually hoards cats, expect at least one of them to be obese.
Most of the time, fat cats are neither mean, a common pet for villains, nor consider themselves to be better than humans. Usually, the fat cat is a common domestic cat, but fat cats of any cat species can count.

- Garfield is famous for using this as its main gag. However, thanks to Art Evolution, Garfield has gotten progressively more and more skinny over the years, to the point that he looks to be around the average weight for most cats now, if maybe a bit more pudgier than the norm. Guess all that dieting wasn't for nothing after all.
- Heathcliff, being the original fat orange cat, was doing this long before Garfield was. Granted, he was nowhere near as fat as Garfield was in the beginning.

Satchel: Ooop! Ha ha! You know, you're actually mostly muscle!
Chubby: I do 200 buddy crunches and hug-ups a day.
- In Beetle Bailey, Sgt. Louise Lugg's Bella looks fat... although it's also been suggested that she's either just got thick fur, or is all muscle. Then again, to begin with, she doesn't even walk because her owner carries her around, so it's not like she's getting much exercise.
