Cats can sleep about 12 to 16 hours a day, and kittens and elderly cats can sleep about 20 hours a day. If the weather is bad, the sleeping time of cats will be increased. Although cats can sleep for more than ten hours a day, they only spend about four hours in true deep sleep. Cats are nocturnal animals, so they need to nap to recharge their batteries and maintain their strength. Therefore, cats sleeping for a long time are not sick. .
