Sleep is an important behavior that animals cannot lack. Sleep can relieve the fatigue of the body and brain, and can prepare forces and energy for the next activity.

Anyone who has raised cats knows that cats especially like to sleep. Except for eating and exercising every day, they seem to be sleeping at other times. However, compared with human beings who usually sleep for 8 hours, the cats who are raised will sleep for 16 hours a day. It can be said that most of their life is spent in sleep.

It is normal for cat owners to see their cats curled up on the sofa, bed, or windowsill sleeping lazily. Although cats love to sleep, young and older cats generally sleep longer than adults. Cats sleep longer when the weather is warm than when it is cold, and longer when they are full than when they are hungry.

Cats can usually sleep for 15-16 hours a day, and these drowsiness habits originated from the history of the evolution of cats. Cats are born with hunting skills. Only when hunting prey or eating, they are the most active. They sleep for a long time to store energy to better hunt prey.

In the wild, cats must hunt to fill their stomachs. This requires a lot of energy. Sleep allows cats to make better rest after hunting, which is conducive to the next hunting. The current pet cats will gradually adjust their sleep time due to the impact of our daily life.

Another reason is the cat's carnivorous lifestyle. Meat is a nutritious high -protein food. In contrast to cats, the nutritional content of the foods eaten by herbivores and other animals is low, so they must keep eating. Because the foods eaten by cats are rich in nutrients, they can spend less time eating and spend more time sleeping.

Studies show that cats spend three-quarters of their sleep time in light sleep. Although cats appear to sleep for 16 hours a day, they are actually asleep for only about four hours.

Cats, like humans, have deep and light sleep. Some people sleep, even when the thunder outside can not wake them up, while others sleep and only hear a slight noise may wake up. By nature, cats are always on alert, so they spend most of their time in a light sleep state.

Usually, we see a cat sleeping, but it might just be in a light sleep state. If we touch it gently, it will be awake instantly. This situation shows that cats are just resting. Cats will always maintain vigilance at any time. This shallow sleep helps maintain the sensitivity of the cat.

We'd better not disturb cats when they are sleeping, or it will affect their health. Because although they sleep for a long time, three-quarters of them are light sleep, and the remaining quarter is the cat's true deep sleep.

This quarter sleeping time is extremely important for cats. If they can’t sleep with peace of mind, then the physical and mental of cats will have problems in the long run. Cats secrete growth hormones while sleeping, and long-term sleep can make kittens grow better. If we disturb their sleep, then it may affect their future health.
