Concerning Cats Sleep Cycles.
Cats can sleep up to 16 hours a day, but, when they wake up they do an interesting ritual. Immediately after waking up, cats usually yawn. (Although other animals like dogs tend to yawn when nervous, this does not apply to cats.) After yawning, cats, which are very flexible, do a series of stretches flexing their necks, legs, paws, and back. And finally, they groom themselves. By the way, did you know that cats have two modes of catnapping? Light sleep and deep sleep. In light sleep the cat can easily be aroused and in deep sleep the cat can flex, twitch, and dream. I know that cats flex, twitch, ect. But I know for a fact that some cats sleep more than sixteen hours a day!
