How long does a rabbit sleep? 11 hours, only one of them deep
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
You will read everywhere that a rabbit sleeps twelve to fourteen hours a day, mostly lightly. Those figures have no source: the only electrophysiological measurement published in this species gives a different picture, and above all a different timetable. Our housing guidance is gathered in the rabbit bedding and habitat section.

11.4 hours, split across three states
Pivik, Bylsma and Cooper published in 1986, in Behavioral and Neural Biology, a study of sleep-wakefulness rhythms in the rabbit (see the study). Adult male rabbits were monitored continuously by electroencephalogram, eye movement recording and neck electromyogram over several consecutive 24-hour periods. The result fits in one sentence: rabbits slept an average of 11.4 hours a day, of which 25.9 % drowsy, 64.5 % slow-wave sleep and only 9.6 % paradoxical sleep.
Converted into durations, that is roughly 2 h 57 a day in an intermediate state from which the animal wakes instantly, 7 h 21 of slow-wave sleep, and barely 1 h 06 of paradoxical sleep across twenty-four hours. A rabbit who always looks half awake is therefore not sleeping badly: that is the normal structure of his sleep.
The counter-intuitive part: rabbits are more awake at night
The authors also report differences by phase of the light cycle: more wakefulness and less paradoxical sleep during the dark phase. In other words, the deepest sleep clusters in the light phase — in the middle of the human day. This dovetails with the crepuscular profile already described in our article on the circadian rhythm of feeding and caecotrophy.
The practical consequence is direct. A dark, secure corner is usually set up "for the night"; on this evidence, it mostly earns its keep in the afternoon. The afternoon is also when household noise — vacuum cleaner, television, coming and going — lands on the most fragile sleep window, as our guide to noise sensitivity in rabbits points out.
What the study does not demonstrate
- These were laboratory rabbits, adult males, carrying implanted electrodes, under an artificial light-dark cycle. The sample size is not stated in the accessible abstract.
- Nothing was measured in home housing: not the effect of a hideout, nor of a companion, nor of noise on these percentages.
- "Paradoxical sleep" does not mean "the rabbit dreams": these are electrophysiological states, not mental content.
- No recent replication appears to have been published. This is the available data, not a finding consolidated by several teams.
Frequently asked questions
My rabbit sleeps with his eyes open — is that normal?
Yes, it is common in this species, particularly in the drowsy state that accounts for a quarter of his sleep time. Ear position and slackness tell you more than the eyelids.
Should the cage be covered at night to help him sleep?
The study suggests night is not his main deep-sleep window. Full darkness overnight therefore misses the point: daytime quiet matters more.
Is a rabbit who sleeps little unwell?
A lasting change in rest time, especially alongside reduced appetite or fewer droppings, warrants a consultation. The absolute figure itself varies a great deal between individuals and settings. Find all our guides on the rabbit hub.
