Many cat owners wonder why their feline friends sleep so quickly. After all, they are adorable when they are snoring! However, most cats spend between fifteen and twenty hours asleep each day, depending on their age. Older cats and kittens sleep more, so it’s no wonder that their cat sleep patterns increase as they get older. Read on to learn more about these incredible creatures and why they sleep so fast!

Sleep spindles
Scientists have discovered that a common characteristic among humans and cats is their sleep spindles. These small bones are essential for good sleep, and their frequency reflects the same neural processes as those in humans. This study could be the beginning of an important new understanding of sleep cycles in cats. Further research is needed to confirm this theory and further explore how sleep spindles can be used to predict human sleep. This is an area that has recently received increasing attention due to its possible use as a model for human ageing, Alzheimer’s disease (AD), and dementia.
While the exact mechanisms underlying the mechanism of sleep spindles are still unknown, it is believed that they open fine-tuned windows of opportunity for cross-regional synchronization and plasticity. Recent work by Das et al. and Laventure et al. has found that the hippocampus and neocortex experience increased functional BOLD connectivity during sleep spindles.
Researchers have discovered that the sleep spindles serve as memory integration sites and mediate hippocampal-neocortical coupling during sharp-wave ripples. The authors of these studies suggest that the activity of sleep spindles is regulated by gamma activity and is increased during excitable troughs of spindle oscillation. Interestingly, the same mechanism also governs sleep patterns in humans.
NREM sleep
Before entering NREM sleep, cats may be alert or lightly asleep. They may even twitch and stretch. REM sleep is similar to human dreaming. Cats can move their eyes horizontally and vertically and produce a variety of strange noises while in this stage of sleep. Here is some information to understand why cats sleep so fast:
REM sleep is different from non-REM sleep in that REM involves rapid eye movement and brain activity that is similar to the awake state. It is during this stage that animals dream. Young animals tend to spend longer in this stage, which is why they process a large amount of new information during the dream state. Cats also appear to fall asleep anywhere, including the sink and toilet. This heightened activity is thought to be related to the REM stage of sleep.
Scientists had long held a preconception about the sleeping brain and the third state of consciousness. Until 1953, REM SLEEP remained hidden. Nevertheless, researchers and cat owners alike were excited to learn more about the process. This discovery led to a 65-pound zinc plaque hanging in the psychiatry department at the University of Chicago Medical Center. Aserinsky’s daughter accompanied him to the event. She was wearing a name tag, so people would be able to identify her when they saw him.
REM sleep
If cats can dream, then they are most likely to experience rapid eye movements (REM) during sleep. During this stage of sleep, their eyes twitch rapidly and they tend to roll over to one side while sleeping. The brain activity during this period is similar to that of waking humans. However, unlike humans, cats cannot fully wake up from this deep sleep. This stage of sleep lasts between five and seven minutes.
The first study of REM sleep in cats was conducted in 1958 by William Dement. It ushered in the ‘golden age’ of sleep research by establishing that cats undergo rapid eye movement (REM) sleep. In that time, researchers were able to observe cats performing a variety of tasks and observing their behavior. The researchers noted that during REM, cats acted aggressively and lost muscle tone.
As a cat grows older, its REM sleep declines, but kittens experience more of it than adult cats do. Their brains contain more information and so they send more signals to each other. REM sleep also allows cats to dream about things and move their heads as though they are watching something. These dreams are likely about hunting. They do not need to worry about being attacked or stalked while they are in this stage of sleep.
