If your cat looks like a beach ball, it might not be because she’s obese. Most cats have what’s called a “primordial pouch.” That’s a cool term for what’s essentially an extra flap of skin under the belly. While it can vary from individual kitty to individual kitty, the primordial pouch is more visible in some cat breeds than others.
A hanging primordial pouch can make it seem as if your cat has put on some flab. But if you inspect your cat’s tummy closely, you can easily tell whether you're dealing with a primordial flap or a case of too many treats.
Some cat breeds are known to have noticeable primordial pouches. The Pixie Bob, the Mau, and the Bengal are cat breeds for which a pouch comes standard. It’s actually a breed requirement. Plenty of other cats have one too, though.
What’s the purpose of a primordial flap? Is your cat cousins with a kangaroo? She probably isn’t, but the surprising thing is that scientists aren’t sure what the pouch is for, either. There are a few reasonable theories, though.
We aren’t quite sure what the pouch is for. It’s quite likely that it’s a combination of all these reasons. But it’s not the only flappy bit of your cat’s anatomy.
Compared to dogs, cats generally have much looser skin. This may have evolved to help them wriggle out of tight spots in the wild. The scruff of a cat--the loose skin around her neck--is a much better-known part of cat anatomy than the pouch. The expression “by the scruff of the neck” comes from mother cats carrying their kittens around by the scruff, using their mouths. You probably don’t want to try this out, though.
It’s important to understand that your cat’s pouch is nothing to worry about. It isn’t a sign of feline obesity, and it’s not an abnormality either. In fact, your cat’s more likely suffering from issues if shedoesn’thave one.
If you’ve noticed that your cat has a primordial pouch, there’s no need at all to worry or get the vet involved. It’s just another part of your cat to love!
