Anyone who has owned cats is well aware that they do not conduct their lives in an order similar to other household pets. For instance, cats may sleep 15 hours or sometimes almost the entire day, then be awake during the night since they are crepuscular (a word meaning relating to twilight). Much more active from dusk until dawn, cats either nap or go into a deep sleep during the day. Some owners who are aware of cats’ nocturnal natures still wonder why they sleep so many hours.

Cats can appear to be asleep for as much as 20 hours, but the depth of their sleep varies. During a third of the time that they are curled up with their eyes closed, cats are in a deep sleep. This level of rest, during which cats dream, is essential to a cat’s health because it is the period in which their bodies regenerate cells, thus allowing the cat to remain healthy.

In the hours in which they are not in a deep sleep, they may just be dozing or resting in case they need energy. They may appear to be sound asleep, yet they can become alert at a moment’s notice and spring into action. This ability is essential to their nature as a predatory animal who must be capable of capturing prey at the opportune moment. When cats lived in the wild, they often hunted for long hours, so they slept as much as possible to have the necessary energy for their hunting. Not having been domesticated as long as dogs, cats retain some of the habits of their ancestors. Taking naps allows them to recharge, just in case they need to spring into action.
Just like us humans, our friendly felines are affected by weather. Although cat behavior will range depending on their breed, age, personality, one thing that is for sure, cats will sleep when the weather is unfavorable. Even if your kitty is primarily an indoor-dweller hey can still feel the affects of a rainy and cold day. Most like you will find them curled up in a blanket when gloomy weather approaches.
Natural instincts and the weather aren’t the only two reasons for a cat’s sleeping pattern. Below you will find a combination of reasons that your very own cat may be snoozing:

1. Kittens who are growing sleep more than adult cats.
2. Older cats need more rest than younger cats.
3. Cats will sleep longer when it is cold so they can conserve energy and remain warm.
4. Cats like to sleep in the sunshine to warm themselves.
5. Cats sleep for long hours if they have been active for several hours.
6. Cats who are bored will sleep more often than others.
