Why do cats curl up when they sleep?

Cats curl up when they sleep mainly for safety and warmth. Cats are actually domesticated from wild animals. When they were still in the wild, due to the many unsafe factors in their environment, they would curl up to sleep to detect sounds in their surroundings, allowing them to escape promptly when they encountered danger.

The reason why cats curl up when they sleep is first and foremost about safety, which mainly stems from their lack of security. Wild cats face many unsafe factors, especially being attacked by other animals. Cats curl up this way so that their ears can directly touch the ground, allowing them to hear other animals' sounds and respond promptly, such as running away or counterattacking. Generally speaking, domesticated cats do not face environmental unsafe situations, so most of the time, they adopt a sleeping position of lying on their side or sleeping on their back, which indicates that they have absolute security. However, if a cat still likes to curl up at home, it may indicate that the house is not safe enough for the cat or that the cat is feeling cold.

For situations where safety is insufficient, it is recommended that pet owners show more affection to their cats, interact more with them, and prepare food and toys that they like. This can help the cats trust their owners wholeheartedly and adopt more comfortable sleeping positions.

For cases where cats curl up due to low environmental temperatures, it is recommended to prepare a warm, comfortable, and wind-proof cat bed. Generally, a cat bed with high edges can be chosen.同时, try to maintain the ambient temperature within a comfortable range, especially during cold winter weather.
