Do All Cats Have a Primordial Pouch?

Primordial pouches are part of the feline anatomy that all cats have. It is easier to notice this abdominal fold when it sways back and forth as the cat runs. The size of the pouch can be large for certain cats; older cats, cats that do not maintain a healthy weight and wild cats can have more pronounced primordial pouches.

Why Do Cats Have Primordial Pouches?

The reasons for the appearance of a primordial pouch in cats are still unknown, but the following are some of the major theories:

Protection: It serves as a shield to sensitive areas of the cat’s lower belly region. The primordial pouch helps shield their vital organs in the fight by adding an additional layer between the claws or teeth and cats inside. It is useful when they fight with dogs or even other cats. It protects your dog’s important organs from damage.

Stretching: The next theory is that the primordial pouch enables the cats to run faster. It stretches as the cats run, which gives them extra flexibility and the ability to go farther with every bound. These qualities can help cats catch their next meal or escape predators.

Storing Food:  The third theory is that the primordial pouch provides extra space for cats to store food after a big meal. In the wild, cats don’t get two square meals a day; they eat when they want and may store food from a big kill in their pouch for days later.

What Is The Range of Primordial Pouch?

The Primordial pouch runs along the span of the belly at the front of the cat’s hind legs; it is most obvious around the back. All cats have this pouch, but the size differs from cat to cat. Previously obese cats will have more visible pouches. It is not directly attached to any muscle; this makes it movable, a bit elastic, and can feel slippery or jellylike when you touch it.

Differentiating Primordial Pouch from Cat Obesity

If you are not sure of the difference between an overweight cat and a primordial pouch, the following are some revealing signs that will let you know whether your cat has a primordial pouch or if it’s overweight:

  • A cat with a saggy primordial pouch will sway from side to side when walking. But if your cat belly doesn’t wiggle as it walks, this is due to the extra fat making their fur tighten.

  • Another difference is that if you look down the length of a cat, you will not see the primordial pouch since it hangs underneath the belly. Conversely, fat will look round as it fills the sides of your feline frame. A fat kitty will look so from all angles, and once you touch the cat’s body, it will often feel solid.

  • If the cat is overweight, its ribs will be hidden from fat. To confirm, you can stroke your cat by the side to see if you can feel its ribs. If you can’t, that could mean your cat needs some weight loss. A primordial pouch will not affect the cat’s ribs.
