Do your cats sleep under the bed? Cats sleep a lot, often in unusual places. In fact, kitties sleep two-thirds-of their life away, up to 16 hours each day. That’s more than any other mammal, except for the opossum and some bats.
We don’t know why cats sleep so much. We theorize that predators with few natural enemies (like cats) sleep for longer periods of time. Some experts believe a cat’s need for sleep increases in direct proportion to the amount of energy kitty requires for hunting. Cat hunting behavior requires a lot of energy.
How Cats Sleep
While humans sleep in marathon eight-hour (or longer) sessions, cat sleep combines short and long naps throughout the day. Habits vary between cats but very old and very young kittens sleep more than robust adults. Sleep time increases on cold, rainy or cloudy days.
Two patterns of brain activity characterized the sleep activity of cats, like that of people and many other mammals. Scientists measured this activity with an electroencephalograph (EEG) that records waves or pulses of activity on a graph.
Kitty brains broadcast little bunched-together irregular peaks while awake. But when dozing, the cat’s brain produces long, irregular waves called slow-wave sleep and lasts fifteen to thirty minutes. He lies with his head raised and paws tucked beneath him as he dozes. Sometimes he actually sleeps sitting up, in which case his muscles stiffen to hold him upright. This way he’s ready to spring into action at a moment’s notice.
Cat Sleep Positions
You’ll know when kitty moves from light into deep sleep: his body relaxes; he stretches out and rolls to one side. His brain patterns change and become smaller and closer together, and are very similar to his waking patterns.
During deep sleep (also called “rapid sleep” because of the quick brain wave movement) cats remain fully relaxed and hard to awaken. This phase only lasts about five minutes, and the cat then returns to slow-wave sleep. Thereafter, rapid- and slow-wave sleep alternates until he finally wakes up.
Interestingly, kittens fall directly into deep rapid sleep without this alternating pattern until they’re about a month old. Cat dreams are born during rapid sleep–twitching whiskers and paws chase dream mice, perhaps.
I’m Awake! Sorta-Kinda-In-A-Way…
The cat’s senses continue to record sounds and scents during up to 70 percent of sleep. That means cats awaken quickly at the squeak of a mouse or smell of a rat. A predictable pattern of blinking, yawning and stretching characterizes slower awakening. First the forelegs, then back, and finally rear legs flex and stretch in turn. Most cats also groom themselves briefly upon first awakening.
Cats are crepuscular creatures, and most active at daybreak and sundown. But they typically adapt to the humans they love, sleeping on the owner’s schedule. So they sleep when you are gone and spend more awake time when you are home.
Why Cats Sleep On You
…Because they can! For many of us, cats that sleep ON the bed with us…and on the pillow, on your head, on your chest, and pretty much in any position they want. Sleeping with us shows incredible trust and love. But today’s Ask Amy addresses those felines that prefer the company of dust bunnies to humans. What’s up with that?
Do your cats have weird sleeping spots? What’s the oddest place your cat likes to nap? Seren-Kitty used to cuddled up in her blue bed on the table beneath the stained glass lampshade. In her youth Seren hung out on damp towels on the tile tub surround in the bathroom. Karma-Kat stretches out on the carpet in the middle of the room and sleeps on his back. At night, he sleeps in the crook behind my knees. Oh, and do your kitties argue over prime sleep spots? And what about pet insomnia? Oy, it never ends!
