Cats often curl up into a ball when they sleep, and this behavior is primarily driven by their need to conserve warmth, especially when the ambient temperature is low. This position is also associated with feelings of security, and it can help protect their vulnerable body parts. This curled-up sleeping posture is particularly common during the colder winter months. The primary reason cats curl up is to retain body heat. When cats sleep in an extended position, they expose a larger surface area to the cold air, leading to significant heat loss. This can potentially cause them to get chilled and even catch a cold.

Additionally, cat's paw pads are heat-dissipating organs and lack fur protection, making them very susceptible to cold temperatures. By curling up, they can tuck their paws into their abdomen, providing additional insulation and warmth. This curled-up position...
