As you know cats are amazing hunters, and there are reasons why they are supreme killing machines. They have incredible instincts to spot prey, can move with lightening precision and have mastered many techniques to make sure they will be successful in their quest. One of their techniques is there wiggle action before they pounce. Although it looks cute and funny sometimes to us, it is essential in their preparation for attack.
The wiggle enables your cat to balance and press their paws into the ground. This allows them to achieve perfect balance in grounding the hind legs to propel themselves and launch at its prey with the precision timing and distance required. This mimics how they catch prey in the wild.
Watch your cat next time they pounce on a toy. Grabbing the toy in their mouth while securing it with their claws. They then flick the toy(prey) into the air so they know they have rendered the prey incapacitated, ready for dinner.
Their wiggle is indeed a great asset.
