Why do cats sleep so much?
Whether it’s a deep snooze on the sofa or a quick cat nap in the sun, cats spend much of their day asleep. Here’s a look at how long they sleep, why they do it, where they like to curl up, and the positions they favour.
How many hours a day does a cat sleep?
On average, adult cats sleep for around 12-16 hours a day. This total is made up of lots of short sleep sessions and a few longer rests. Kittens and elderly cats typically sleep more than healthy adult cats - some can doze for as long as 20 hours a day.
Reasons why cats sleep
There are a variety of reasons why cats sleep so much, and several factors that influence how much rest they need:
- Conserve energy: Cats evolved as crepuscular predators, meaning they’re most active at dawn and dusk. Long rest periods help them conserve energy for hunting or short bursts of activity.
- Age and growth: Kittens need lots of sleep to support their development, while older cats may rest more due to decreased stamina and sometimes health issues.
- Weather and season: Cats often sleep more in cold weather to conserve heat and calories, so you may notice extra dozing in winter.
- Health and medication: Illness, pain, or medication can increase a cat’s need for sleep. If extra sleep is accompanied by lethargy, reduced appetite, or other symptoms, it’s best to see a vet.
- Boredom or environment: Cats with little stimulation may sleep more simply out of boredom (particularly indoor cats). Providing play and enrichment can reduce daytime snoozing and encourage healthy activity.
Where should my cat sleep?
Cats tend to prefer warm, quiet, and secure spaces to rest. As an owner, you can provide a comfortable, draught-free bed in an area where they won’t be disturbed too much. High perches or hiding spots can also help your cat feel safe. Many cats enjoy sunny windowsills, cat igloos, a blanket-lined box, or simply their favourite chair or even the bottom of your bed! Offering a few options helps reduce stress and gives them control over their environment.
Is my cat sleeping too much?
The amount a cat sleeps can vary between individuals, so it’s tricky to say what’s “too much.” The main thing to watch out for are changes in your cat’s sleeping habits, as these can be warning signs. Ask yourself: is your cat less responsive when they’re awake? Has their appetite or litter-box use changed? Are they having mobility issues or coughing/retching? If you notice any changes in their behaviour or physical health, alongside increased sleep, it’s best to book a vet appointment. Otherwise, long naps that end with normal behaviour are usually fine.
Seasonal changes in sleep
Cats, like humans, can be affected by seasonal light levels. During shorter winter days they may rest more, echoing the natural rhythms of their wild ancestors. In warmer months, they may be more active - but long naps in sunny spots are always a favourite!
How to encourage healthy sleep in your cat
You can support healthy sleep patterns for your cat, which helps with their overall wellbeing. Here are a few tips:
- Offer interactive play before bedtime, which mimics natural hunting cycles.
- Stick to a feeding routine so your cat knows when to expect food.
- Provide scratching posts, toys, and views from a windowsill to prevent boredom.
- Keep up with regular vet care to rule out health issues that might cause excessive lethargy.
- Make sure sleeping spots are safe and quiet - away from open windows, washing machines, or tight spaces.
- Avoid disturbing a sleeping cat, especially during deep sleep. Startling them can cause stress or defensive behaviour.
My cat twitches in their sleep – are they dreaming?
Yes. Like humans, cats go through REM (rapid eye movement) and non-REM sleep. During REM, you may notice their whiskers, paws, or tail twitching – these are all normal signs they’re dreaming.
Cat sleep positions
You’ve probably noticed your cat resting in all sorts of positions, often favouring one or two regulars. This choice can show you how safe and comfortable they feel. Here are some common cat sleeping positions:
Curled in a ball: Conserves heat and protects vital organs. Common when a cat wants to feel secure or warm.
Stretched out: Sprawling shows they feel relaxed and safe. It also helps them cool down.
On their back with head upside down: Exposing the belly is a sign of trust and relaxation (though not always an invite for belly rubs!). Cats may tilt their head upside down when they’re especially content.
Loaf position (paws tucked): A lighter sleep state - cosy but alert, ready to wake if needed.
Why does my cat sleep on me?
Your cat sleeping on you is often a sign of trust and bonding (plus they love your warmth!). They may find your body heat comforting and see you as part of their safe territory. Kneading and purring while settling are also signs of affection rooted in kittenhood. If your cat chooses you over other spots, take it as a compliment (but still provide alternative options too).
Why does my cat sleep on my bed?
Your bed is warm, quiet, and smells like you - all big pluses for a cat nap. Cats may sleep at your head or feet for warmth, security, or to guard their chosen territory.
Kittens and sleep
Kittens may sleep up to 20 hours a day. Rest is vital for their growth, brain development, and immune system. They’ll also wake often for bursts of play and feeding. Make sure they have quiet, warm areas for sleep away from household noise.
Senior cats and sleep
Older cats also tend to rest more, often preferring soft, warm beds that ease any joint stiffness. Like elderly humans, they may nap more lightly and wake more often. If an older cat’s sleep suddenly increases or decreases, it may indicate pain, arthritis, or other conditions, in which case a trip to the vet is a good idea.
Cat insurance
Since sleep changes can sometimes signal health problems, having cat insurance can give you peace of mind that you’ll always be able to get your cat the care they need.
