The reason why cats sleep on their backs.

The cat is very relieved about the current surrounding environment and knows that nothing that makes it feel dangerous will harm it. The environment around the home has a sense of dependence and belonging, and it feels like this is its territory. If the owner finds that the cat is sleeping on its back, it is okay to ignore it. This is not an abnormal behavior of the cat and will not be harmful to the cat.

How many hours do cats sleep a day.

It is normal for cats to sleep 15 hours a day, and for kittens to sleep about 20 hours, but the time that cats really sleep is only about four or five hours. Adult cats will be half asleep and half awake when sleeping, with deep sleep and light sleep alternating with each other. Cats are predators, so a half-asleep and half-awake state can help them maintain adequate physical fitness and help them observe their surroundings.
