Why Do Cats Sleep So Much? Normal Sleep and When to Worry
If your cat spends most of the day in a sunny patch or curled on the bed, you are not imagining things. Cats are champion sleepers. Understanding why can help you tell a normal nap from a sign of illness, and adjust routines so everyone gets a good night's rest.
How much do cats sleep?
Most adult cats sleep 12 to 16 hours in 24. Kittens and seniors can sleep 18 to 20 hours. This can look like laziness, but it is built into the cat's biology.
Wild cats are predators that hunt in short, intense bursts. Stalking and pouncing use a great deal of energy, so the body conserves it between hunts. House cats retain the pattern even though dinner comes from a bowl.
Types of sleep
Cats cycle between:
- Light dozing, when they are semi-alert and ears may twitch at a sound. This makes up much of their sleep.
- Deep sleep, when muscles relax, whiskers twitch and dreaming occurs.
Cats may wake easily during light sleep and return to naps many times a day. This is normal.
Crepuscular rhythms
Cats are crepuscular, which means most active at dawn and dusk, the times when small prey is most active. That can lead to early-morning wake-up calls and evening zoomies, as explained in why do cats meow at night. Your cat is not trying to annoy you. It is following instinct.
Sleep at different ages
Kittens. Growth takes energy, so kittens sleep a lot, in between bursts of play. See kitten feeding schedule for the meal routine that supports growth.
Adults. Typically 12 to 16 hours, with active periods of play and exploration.
Seniors. Often sleep more, sometimes because of arthritis, reduced energy or illness. See the senior cat care guide.
Why cats nap where they do
Cats choose warm, safe, elevated or enclosed places. Sunbeams, heated floors, boxes, laundry baskets and your lap all work. Cats prefer to sleep where they feel secure, and where they can see an exit. A cat that suddenly changes its sleeping spot, such as hiding in a closet or under the bed, may be stressed, unwell or in pain.
Sleep positions
- Curled in a ball: conserving heat, feeling secure.
- Loaf, with paws tucked: relaxed but ready to move.
- Stretched out on the side or back: deeply comfortable and trusting.
- Belly up: feels very safe, though it is not always an invitation to pet.
Shifting the schedule
If your cat wakes you at night, try these steps:
- Play intensely in the evening, with a wand toy for 10 to 15 minutes, mimicking a hunt.
- Feed a meal after play, which fits the natural hunt, catch, eat and sleep cycle.
- Keep daytime stimulating, with window perches, puzzle feeders and toys. See indoor cat enrichment ideas.
- Avoid rewarding night-time demands, since attention teaches the cat to repeat it.
- Use an automatic feeder to give a small breakfast without your involvement.
- Make the bedroom a calm zone, and close the door if needed.
When sleep signals a problem
Call your vet if you notice:
- A sudden increase in sleeping, or reduced activity
- Hiding, avoiding contact or not coming for food
- Loss of appetite or weight
- Increased thirst or urination
- Difficulty breathing while asleep
- Vomiting or diarrhea, as covered in cat vomiting causes
- Stiffness, limping or reluctance to jump
Cats hide illness, so behavior changes are often the first sign. See the emergency warning signs guide. Use the US vet directory to find a clinic.
Too little sleep
A cat that rarely rests, paces or calls constantly may be anxious, in pain, hyperthyroid or have cognitive decline. Ask your vet to check, especially in older cats.
Sleep and the household
Cats adapt to the people around them. A cat that lives with someone who works from home may nap in shorter stretches and join in activity, while a cat left alone all day may save its energy for evening. Keep light, noise and temperature comfortable, and give each cat more than one sleeping spot so it can choose. In multi-cat homes, a favorite bed can become a source of tension, so provide extra beds at different heights. Sleeping cats should be left alone where possible, since waking a cat suddenly can startle it, and some cats react with a swat.
Kittens and sleep safety
Very young kittens should always have a warm, draft-free place to sleep, with a litter box and food nearby once they are weaned. If a kitten seems limp, cold or hard to wake, contact a vet at once, since this is different from normal deep sleep.
Sleep and enrichment
Bored cats may nap more and then be restless at night. Rotate toys, give climbing spaces and schedule play. Quality sleep follows quality activity. Safe, quiet sleeping places also help, so provide beds in several rooms and consider a heated pad for older cats.
