Why does the cat shake its hind legs? - in detail
Cats exhibit a unique behavior where they shake their hind legs, often referred to as "kneading" or "making biscuits." This action is not merely playful but holds significant meaning in feline communication and psychology.
Firstly, kneading is a remnant of kittenhood when cats would press on their mother's belly to stimulate milk flow during nursing. As they grow older, this behavior becomes associated with comfort and security, serving as a self-soothing mechanism. When an adult cat kneads, it often signifies contentment or relaxation, indicating that the cat feels safe and at ease in its environment.
Additionally, cats use hind leg shaking as a form of territorial marking. During this action, scent glands located on the pads of their feet release pheromones onto the surface they are kneading. This olfactory signal communicates to other cats that the area is claimed and marked by the kneading cat, reinforcing its territory.
Moreover, hind leg shaking can be a precursor to more intense feline behaviors such as hunting or fighting. In these contexts, it helps to prepare the cat's muscles and tendons for sudden bursts of speed or agility required in pursuit or combat. The action stretches and loosens the leg muscles, ensuring they are ready for quick and precise movements.
In conclusion, cats shake their hind legs as a multifaceted behavior rooted in both instinctual and learned responses. It serves to express contentment, mark territory, and prepare the body for physical exertion, offering valuable insights into the complex communication system of these fascinating creatures.
