Why Do Cats Wiggle Before They Pounce?

If you're lucky enough to have a bundle of loaf at home - sometimes referred to as the rent-free addition, the mighty mitten wielder, or the resident baker - you might have found yourself wondering the same thing: why do cats wiggle before they pounce? After all, there's nothing quite like seeing a cat ready to get its paws on the latest hunt.
The widening eyes, the poised triangles, and that little wiggle might be funny to watch, but there is more of a reason behind why cats have their signature move before they pounce than meets the eye. At least, experts have plenty of theories about why cats might wiggle before they pounce, even if there isn't a definitive answer.
