Why Do Cats Sleep So Much?.

Why Do Cats Sleep So Much?. How much do cats sleep? Cats sleep between 15 and 20 hours a day! This is twice as much sleep as most other mammals need. Cats get that much sleep by taking naps throughout the day and night, rather than sleeping for 18 hours all at once. Cats are crepuscular. This means that they are the most active during twilight times (dusk and dawn). During most other times of the day, they are either snoozing or in a deep sleep. Snoozing refers to the type of sleep when cats are usually sitting upright with their eyes partly open, and their ears twitch in response to noises. Cats are in a half-asleep state when they are snoozing, and about 75% of a cat's sleep-time is this type of sleep. During deep sleep, cats are usually curled up, eyes completely closed, and they sometimes have their faces covered by their paws or tail. The well-known term "catnap" pays homage to these extraordinary feline sleeping abilities and styles.
