Why does a cat's belly hang?

After a cat is full grown we sometimes notice they have a bit of a belly pooch. It looks like an extra flap of skin and fur that hangs down on their belly area. This often looks like just loose skin but it's more than just that. This is something called the primordial pouch, and it's nothing to be worried about.

Extra skin on cats belly is called a primordial pouch

Even though this flap of loose skin swing side to side and seems like it would be a hindrance to your cat, it's not. This pouch can be present in male or female cats and it also referred to as an abdominal flap or abdominal fold. This pouch is not a result of gaining weight or being spayed. It's actually parts of a cat's defense system.

We all know that claws are a cat's first line of defense from a threat. Teeth are also used as protection but that belly pooch is actually also part of a cats defenses. When cats fight each other they wrestle around and kick each other with their back feet. They will often kick against the other cat's abdomen. This loose flap of skin and fur protects their internal organs from this type of blow during a fight.
