Video: How Does A Cat Sleep?
A few words about this amazing feline feature. A cat spends an astonishing amount of time sleeping. Her particular anatomical and physiological structure shows that her body is adapted to act in a sudden impulse. A predator does not need endurance and endurance, but hard work in a short period of time and at a short distance. Accordingly, cats get great pleasure from rest and respite.
A love of comfort - a warm spot on the windowsill, under a desk lamp on a desk, or a favorite pillow - is an important feature of their lifestyle. In general, a cat sleeps sixteen hours a day, sometimes only for a few minutes - the so-called "nap". Why our murka sleeps longer than other mammals is unclear.
Whether the cat is asleep or awake, it continuously receives information from the surrounding world. In one scientific experiment, a cat was placed in such a way that it did not receive any signals from the outside, and an encephalogram of the brain was taken. The result is this: in this case, the cat's brain perceives only the work of its own body. There is no evidence of unexpected decisions or considerations; the cat, of course, will not write poetry or remember different incidents from its rich past, like people who find themselves in a similar situation.
The brains of sleeping cats have also been studied using encephalograms; at the same time, the stages of deep and superficial sleep were recorded - respectively 30% and 70%. These phases alternate: you can follow the external manifestations of this state: the movements of the paws and claws, twitching of the mustache, wiggling of the ears, in some cases the animal makes different sounds in a dream.

It is curious that the brain of a cat, while in deep sleep, is as active as in the minutes of wakefulness, and is constantly alert to perceive the danger signal that is sent through the sensory apparatus. So do not try to pull the sleeping cat by the tail with impunity, believing that you will be able to hide from retaliation: it will wake up instantly.
The cat yawns frequently and continuously - before falling asleep and after waking up. Then she diligently stretches and, keeping her paws close to each other, arches her back in an arc. The tail at this time hangs sluggishly down, the head is lowered. Then she shakes all the limbs in turn, starting usually with the first step with her front paws. Often after that, it stretches out to its full length to sharpen its claws - against a tree, against a wall or furniture in the house. But this is already a topic for another conversation.
