Cats sleep an average of 15 hours a day, and some can sleep up to twenty hours in a twenty-four hour period. So why do cats sleep so much?
The thing we all know is that cats are most active when you are asleep, which means that they sleep mostly during the day and become active around twilight. This can come as quite a shock if you’re bringing a new kitty home for the first time. Your cat will waste no time investigating and getting into trouble — usually while you’re fast asleep! But as soon your cat is done with breakfast, as the rest of the world winds up for action, you’ll find him winding down for a long day of slumber.
Cats have the physiology of a predator, meaning that they’re hardwired to give chase and hunt — mainly at night. Large cats such as lions have a similar pattern of sleeping during the day and hunting at night. Although they have been domesticated for the most part, housecats still retain that wild streak. Even cats at play will display the feline primal instincts of creeping about in the shadows and, without a whisper of warning, pouncing on their target prey.
And hunting prey takes an amazing amount of energy. Whether your kitty is hunting for outdoor prey or tackling a catnip toy, all that sleep he gets is reserve energy for running, pouncing, climbing and stalking.
