What makes cats sleep so much?

1. Natural Environment

Cats are predators, and they've hunted for living all through history, both ancient and modern. When they are hunting, their bodies must provide lot of energy and water to compensate for the exertion, and all felines must sleep to replenish this water and energy. 
Domestic cats retain predatory physiological instincts, despite the fact that the majority of them have been domesticated.  They are conserving energy and preparing for "explosive" hunting by resting.

In addition, felines are pure carnivores, and cats on high-calorie diets need to spend extra time sleeping, reducing caloric consumption between meals and extending the time interval between hunting again.

2. High Vigilance

Cats must get enough sleep during the day to have sufficient energy to catch prey since they must hunt at night. Because surviving in the environment is risky and difficult, they sleep during the day but remain vigilant at all times, not resting entirely.
Even pet cats have the same naturally high alertness psychology, therefore cats must sleep through a variety of lengths to supplement this part of the body's energy consumption. This vigilance demands a large body of energy consumption.

3. Cats have sleep cycles just as humans do

Cats sleep lightly and deeply, just the same as people do. A cat positions its body so that it may instantly get awake and respond to sounds when it is in light slumber, which lasts for fifteen to thirty minutes. The cat will experience quick brain waves when it is sleeping deeply.
The cat usually resumes light sleep after about five minutes of deep sleep. Up until the cat awakes, this pattern of deep and light sleep continues.
A cat who sleeps all the time seems to have a physiological habit of looking for food at night and sleeping during the day, as well as excessive sleep fragmentation and a short time to enter deep sleep.

How can you recognize if your cat sleeps deeply or just pretends to sleep?

Step 1
: observe its external reactions. For example, it basically doesn't respond to external sounds, and it doesn't respond when shaking its head or eyes with its hands. Gently pull out the cat's eyelids with your hand, and you can see a layer of white film covering the eyeballs. Then at this time, it must be really asleep, or it must have been in deep sleep just now.

Step 2: In response to external sounds and physical touches, open the cat's eyelids with your hands to see the eyeballs directly. At this time, it must not have had a deep sleep, or be dozing off.

Step 3: Generally, cats that enter deep sleep will maintain a position of lying on their sides, relaxed limbs, or head and buttocks curled together, while those that take a lying position to sleep are generally napping or shallow sleep.
