Cats can sleep for 16 hours, while older cats can sleep for 18-20 hours! They seem to be born to sleep. On rainy days, I sleep almost all day. If a cat lives for 18 years, its non-sleep time is only 6 years.

Cats sleep about twice as long as humans. A cat can sleep for 16 hours a day, and older cats can sleep for 18-20 hours! They seem to be born to sleep. On rainy days, I sleep almost all day. If a cat lives for 18 years, its non-sleep time is only 6 years. Research shows that three-quarters of a cat's sleep is false sleep, that is, a nap. Therefore, it seems that cats sleep for 16 hours a day, but in fact they only spend 4 hours in deep sleep.

Cats sleep in turns of light sleep - deep sleep - light sleep, and most of the time they are in light sleep and "want to sleep". Only when you are completely relaxed will you enter deep sleep, which is about 5 hours a day. Cats who are in deep sleep begin to behave differently when sleeping. If they have another sweet dream, they will become even more unsightly.

Lethargy - this word does not mean sleeping for a long time, but also means that the cat becomes depressed, does not like to move even if it is not sleeping, and the place where it sleeps is no longer the place it liked before (for example, it is more willing to go to the cool place) places, nooks and crannies where no one is)

Sleeping position - instead of sleeping in its favorite position, it rests restlessly, constantly changing positions, or sleeping on its stomach.

Sleep time has increased - more than the normal sleep time of cats, and it is different from the previous sleep time (for example, I used to sleep for a while, get up to eat and play for a while and then go to sleep again, but now I sleep all the time, except for going to the toilet)

Sleep quality - Normal cats will be full of energy and lively immediately after going to bed, but sick cats will be listless when they sleep, and they don’t want to eat or play.
