Why do cats sleep so much?

Cats have evolved to sleep for long periods throughout the day. Wild cats need to sleep in order to conserve their energy to hunt, chase and kill their next meal.

What is the normal amount of sleep for a cat?

The  number of hours that your cat needs to sleep and the typical sleeping pattern for your cat will change as they get older:

  • Kittens will likely sleep most of the day, with a few brief bursts of energy between meals.
  • Adolescent cats may have erratic sleep patterns combined with periods of intense playfulness.
  • Adult cats tend to have more set sleeping schedules that average out at about 12 - 20 hours of sleep each day.
  • Senior cats will tend to have less energy and reduced mobility which means they will sleep more than younger cats.

You will likely find that once your cat reaches adulthood they will begin to form a recognizable pattern of sleeping and wakefulness. For example, you may notice that your cat wakes just before you in the morning, enjoys an hour or two of eating and socializing with you, then returns to sleep while you get on with your busy day.

Is my cat really asleep?

Cats do sleep deeply but not always. Much like people, cats are often just snoozing. Light sleeping makes up about 3/4 of your cat's sleep time, with just 1/4 of their sleep time being devoted to deep sleep.

When cats are snoozing lightly they get the rest they require but they're still alert. When your cat is snoozing or napping you may notice that their eyes remain slightly open or that their ears still twitch and rotate towards noises.
