ONE EYE OPEN
Like people, cats either doze in a light sleep or sleep very deeply. When your cat dozes (which lasts about fifteen minutes to a half hour), he will position his body so that he can spring up and into action at a moment’s notice.
During deep sleep, cats experience rapid (or quick) brain movement. Deep sleep tends to last about five minutes, after which the cat goes back to dozing. This dozing-deep sleep pattern goes on until the cat wakes up.
Kittens and older cats tend to sleep more than the average-aged adult cat.
It should come as no surprise that cats are affected by the weather, just like us. Cat behavior can vary greatly, depending on their breed, age, temperament and overall health. But, whatever your kitty’s usual disposition, it has been observed that cats sleep more when the weather calls for it. Yes, even if your kitty is an exclusive indoor-dweller, a rainy or cold day will have him (and probably you) yawning and looking for some shut-eye.
