The Cats Primordial Pouch This small fold of skin under a cats belly is a natural feature found in many feline species. It develops in adulthood, even in slim cats, and serves several important purposes. Wild heritage: a physical reminder of the cats wild ancestors and their natural adaptations. Energy reserve: holds a thin layer of fat that can be useful during periods without food. Flexibility and agility: allows greater freedom of movement during jumps, stretches, and running. Abdominal protection: acts as a soft cushion to protect vital organs during play or fights. This pouch is not a sign of excess weight but a functional part of feline anatomy designed for survival and mobility.
