Do cats dream?

Probably yes, but it can't be proven for certainFact

Cats experience REM sleep, the stage most closely linked with dreaming in humans, and they show the same kinds of movements we associate with dreaming. Because cats share many of our sleep patterns, experts think it is likely they dream in some form, though we cannot know for sure what, or whether, they dream.

Steps

What the science actually saysFact
  • The honest answer on whether cats dream is: probably, but we can't know for sure.
  • Cats experience rapid eye movement (REM) sleep, the stage most closely associated with dreaming in humans.
  • Because cats share many of the same sleep patterns as people, scientists believe some form of dreaming is likely.
  • There is no evidence of what cats dream about, so claims about specific dream content are guesswork.
How dreaming shows on the outsideFact
  • During REM sleep cats may twitch their whiskers, flick their ears, and move their paws or legs.
  • You may also see rapid eye movements beneath closed lids and hear small noises or quiet vocalisations.
  • These behaviours are usually completely normal and reflect nervous-system activity during sleep.
  • A few sleep-induced twitches usually mean your cat is simply dreaming.
How much of a cat's sleep is dream-capableFact
  • Most adult cats sleep for around 16 hours a day, and some sleep even longer.
  • Cats cycle through light sleep and short spells of deep sleep.
  • Around a quarter of total sleep time is spent in very deep sleep, where dreaming is most likely.
  • Each bout of deep sleep is short, typically about 5-7 minutes.
  • Estimates of total daily sleep vary from about 15 hours up to 20 hours in some cats.

Normal vs keep-watching

Normal: A cat sleeping many hours a day and showing brief twitches, eye movements and quiet noises during deep sleep.

Keep watching: If you are curious, note when in a nap the twitching appears; it usually comes in the short deep-sleep bouts rather than throughout the whole rest.

When to contact a vet. Dreaming itself needs no action. Seek a vet if movements happen while the cat is awake, or come with stiffening, drooling or loss of awareness, as these are not dreaming.

What changes this answer

  • Whether movements occur only during sleep or also while awake
  • The cat's age (kittens spend more time in REM)
  • Whether any other symptoms accompany the movements

Common mistakes

  • Believing we know what cats dream about (there is no evidence for this)
  • Reading every sleep twitch as a health problem
  • Waking a cat to 'check' on harmless dream movements
