Have you ever wondered why cats wiggle their butts before pouncing?

Me too.

It turns out that it is more straightforward than I imagined. Basically, it’s how they brace themselves for the pounce:

Cats are lovely creatures that never fail to amaze us. They are full of quirks and often have a lot of spontaneous antics that keep everyone in the house amused. Cats have a cute little tush that they are proud to show off. They often like to wiggle and shake their hind quarters when they are about to pounce. It is cute and adorable, but why do they do that?

Let’s look at cats’ wild cousins, the big cats. Wild cats such as tigers, lions, leopards tend to grind the ground with their hind quarters before they pounce. It is a way for them to get into position and brace themselves before they attack. Domestic cats share a similar feature – instead of grinding the ground with their hind legs, they wiggle their behind vigorously to attain balance and leverage.

It’s like runners pushing back against the starting block.
