Some cat owners have noticed that their pets have sagging bellies and have worried that they might be overweight. But instead of this being a sign of obesity, those sagging bellies are actually what’s known as a primordial pouch.

These pouches are made up of fat and excess skin and are a genetic inheritance from their feline ancestors. The purpose of primordial pouches is to help cats survive in times of food scarcity.
