Is there many people curious about why cats are rolled into a ball when they sleep? In fact, cats are rolled into balls when sleeping to keep warm and safe. Rolling into clumps protects their necks and heads, while also tightening their bodies to reduce heat loss.

cats are rolled into a ball when sleeping, so that the body's heat dissipation area is minimal, which is conducive to keeping warm and not too cold. In the process of continuous evolution, cats have gradually formed this habit to better adapt to the natural environment. Especially in winter, cats prefer to keep their shrinking posture so that their body temperature is easier to rise.

Sometimes cats crouched in a ball to sleep, maybe because of distrust of the owner, or because the cat just changed into an environment that it was not familiar with. This posture is a defensive posture for strange environments and strangers. When you shrink yourself into a ball, the cat will feel a sense of security.
