You must also wonder why do cats sleep so much? Well, that is because they are asleep most of the times. However, you don’t need to worry about it because it is not just your cat that does this but all the cats love sleeping and this is what they pretty much do all day other than being clingy and eating their meals!
How long do cats sleep in a day?
On an average, cats sleep for a total of 15 hours per day. Some cats like the old cats or young kittens even stretch this to a 20-hours sleep. In old age cats get exhausted easily while the younger kittens do not have much stamina to begin with.
The question is these two getting tired easily and sleeping away throughout the day makes sense, but what is wrong with the rest of them?
Cats need time to recharge
Cats have a built-in mechanism to cope with their hunger and dietary needs. This mechanism is predation. Cats are predators by default while their prey is very quick and elusive.
They run around after their prey, pouncing and sneaking to catch their food. All this use of physical effort requires a lot of recharging. Cats meet their need of physical recharging by sleeping.
Cats are not your regular predators but crepuscular predators. Crepuscular predators are the animals which are active during the twilight period of the day to hunt for their prey.
The reason for them to be up at the time of twilight is that their prey i.e. rodents, small birds etc. are also active in that part of the day. The rest of the day, cats spend while sleeping.
Types of cat-sleep-cycle
Cats have two types of sleep cycle.
- Slow-wave sleep (SWS) cycle
- Rapid eye movement (REM) sleep cycle
About three-fourth of cat’s sleep is a very shallow, ready-to-wakeup sleep. This sleep cycle is known as slow-wave sleep (SWS). The senses of smell and hearing in cats are active in this phase of sleep.
slow-wave sleep cycle. Cats in this sleeping phase look very peaceful but always poised; always ready to react.
You need to be careful because if you pet your cat while she is in slow-wave sleep, she might actually scratch you real bad. These naps last for about 15-30 minutes.
However, the other one-fourth of the times cats really are in a deep sleep. This phase is called the REM sleep in most mammals. Usually when cats’ paws tremble and they look like they are dreaming, they are actually dreaming!
Now you must be thinking that this is all about the cats in the wild that get exhausted from all that wild chase after their prey and compensate it by sleeping all day, but what about the pets/domestic cats who never leave their houses but still sleep all day long.
The answer is, hereditary trait! Cats as a species even if they are domestic or are sleeping in the streets love sleeping to recharge their bodies or even when they’re bored they just sleep!
