Your cat’s been asleep for most of the day. They got up to eat, moved to another spot, and settled down again. You’ve seen them do that before, but lately it seems to be happening more often.
A change in routine, stress, or medication can affect a cat’s sleep. So can pain or illness. If your cat is sleeping more than usual, look at what else has changed: their appetite, the way they move, their litter box habits, and how they act when they’re awake.
If your cat is difficult to wake, struggling to breathe, collapsing, or straining to pee with little or no urine, seek emergency veterinary care right away.
Sleepy or Lethargic? Watch What Happens When They Get Up
A cat having a sleepy day will often seem like themselves once they’re up: interested in a meal, comfortable walking around, and willing to join in the things they usually enjoy. Lethargy in cats is an unusual drop in energy or responsiveness that continues while they’re awake.
You may notice your cat getting out of bed only to lie down a few steps away, or sitting through the evening playtime they normally look forward to. Spending more time out of sight can also look like extra sleep, especially when you can’t tell whether they’re napping or quietly hiding.
Check how much food is actually being eaten. Skipping a meal, leaving most of breakfast behind, or walking up to the bowl and then turning away are changes worth reporting. Movement matters, too. Hesitating before jumping onto the couch, taking the stairs slowly, or staying on one floor may point to discomfort.
Eating normally and moving comfortably are reassuring, but they don’t rule out an early problem. Call your vet if your cat remains unusually quiet or withdrawn, or if the change in sleep keeps happening.
How Much Sleep Is Normal for a Cat?
Many adult cats sleep around 12–16 hours a day, spread across several naps. Kittens and some older cats may spend longer asleep. Individual routines vary, and quiet resting can be easy to count as sleep.
Cats often have bursts of activity around dawn and dusk, although life with people can shift that schedule. If you’ve started working from home, you may simply be seeing naps that were already happening while you were away.
Use the usual sleep range as background information. A clear change in your cat’s own pattern matters more than whether today’s total falls within an average.
When to Call Your Vet
Go to an emergency clinic now for these signs
- Open-mouth breathing at rest, gasping, or obvious effort to breathe.
- Collapse, inability to stand, or very little response to your voice and gentle touch.
- Blue, gray, or very pale gums.
- Repeated attempts to urinate with little or no urine coming out.
A urinary blockage can become life-threatening quickly. Male cats are at greater risk, but any cat struggling to pass urine needs immediate attention.
Call the same day when extra sleep comes with other changes
Contact your veterinarian if your cat is also eating less, vomiting, having diarrhea, hiding unusually, moving painfully, drinking much more, or seeming weak when awake. A sudden, substantial drop in activity deserves a call even if you haven’t spotted another symptom.
Sleeping more and not eating is especially concerning. An adult cat that has gone about 24 hours without food needs urgent veterinary attention. Call earlier when appetite loss comes with low energy or other illness signs; the 24-hour mark is not a waiting period. Kittens that stop eating need prompt advice because they can deteriorate faster.
A small increase in napping can be watched over the rest of the day when an otherwise healthy adult cat is alert, eating normally, moving comfortably, and using the litter box as usual. Call if the change continues into the next day, keeps returning, or gets worse. Seek advice sooner for a kitten, a senior cat, or a cat with an existing medical condition.
What Might Be Behind the Extra Sleep?
A quieter routine or less to do
Think about what has changed recently. A family member may be away, regular playtime may have slipped, or your cat may have lost access to a favorite lookout spot. Fewer chances to explore and play can leave an indoor cat spending more time resting.
For a cat who is otherwise well, offer a short play session when they’re already awake. Move a wand toy along the floor, let them catch it, and stop when they lose interest. Rotate a few toys or make a comfortable window perch available. Put string and wand toys away after supervised play.
Enrichment supports healthy activity. A sudden loss of interest in familiar games still needs attention rather than being automatically labeled boredom.
Stress may change where they spend the day
Visitors, renovations, a move, or tension with another pet can change a cat’s routine. A cat staying in the bedroom all afternoon may be avoiding a busy household, and you may not be able to tell how much of that time is actual sleep.
Offer a quiet retreat and keep meals and interactions predictable. In a home with multiple cats, check that each cat can reach food, water, litter boxes, and resting places without another cat blocking the way.
Let your cat approach you at their own pace. Persistent withdrawal, reduced appetite, or reduced activity should be discussed with your vet, even when there’s an obvious source of stress.
Life stage changes
Kittens need plenty of sleep while growing, but they should still have periods of age-appropriate activity and interest in food. A kitten who suddenly stops playing or becomes weak needs veterinary attention.
An older cat sleeping more may have a different daily rhythm than they did a few years ago. That makes gradual changes easy to overlook. Sleeping downstairs, for example, could reflect difficulty using the stairs or reaching a favorite bed.
Tell your vet about changes in jumping, grooming, nighttime behavior, weight, or litter box use. Arthritis, dental problems, and other conditions can affect a senior cat’s activity and comfort. Getting older should not mean leaving those changes unexplored.
A recent prescription, vaccination, or procedure
Some medications, including gabapentin, can cause drowsiness. Sleepiness may also occur after anesthesia, and mild tiredness can follow vaccination.
Check the instructions your veterinary team gave you. Ask how much drowsiness to expect, how long it should last, and what changes should prompt a call. The answer depends on the medication or procedure and your cat’s health.
Contact the clinic about sleepiness that seems excessive, is worsening, or lasts beyond the expected recovery period. Get veterinary advice before changing medication doses. Difficulty breathing or being barely responsive requires emergency care even after a recent treatment.
Pain or an underlying illness
A cat in pain may spend more time still because moving is uncomfortable. Look for hesitation before jumping, stiffness after resting, reduced grooming, or sensitivity to being touched. A cat doesn’t have to limp or cry to be hurting.
Illness can also reduce energy. For example:
- Kidney disease may cause increased thirst and urination, weight loss, poor appetite, and lethargy as it progresses.
- Anemia, a shortage of red blood cells, can cause weakness and reduced activity. Very pale gums or breathing difficulty need urgent attention.
- An infection with a fever may leave a cat unusually quiet and less interested in food.
These conditions can share symptoms, and extra sleep alone cannot tell you which one is present. Your veterinarian may recommend an examination, blood tests, or urine testing based on the changes you’ve noticed.
What You Can Do at Home
While arranging veterinary advice, keep your cat’s surroundings calm and make food, fresh water, and a clean litter box easy to reach. A comfortable bed on the floor can help a cat who seems reluctant to climb.
Write down a few observations for the clinic:
- When the change started. Include whether it appeared suddenly or built up gradually, plus any recent medication or household changes.
- What they’re actually eating. Note meals and approximate amounts. In a multi-cat home, a partly empty shared bowl doesn’t show which cat ate.
- What’s happening in the litter box. Watch for changes in urine clumps, stool, frequency, and straining. Do not delay care to collect more information if your cat may be unable to urinate.
- How they move and interact. A short video of unusual walking or hesitation can help your vet, as long as recording it doesn’t delay treatment or distress your cat.
Keep water freely available, including if your cat is drinking more. Increased thirst is useful information for the vet. Suspected dehydration needs veterinary assessment; simply putting out another bowl may not correct it.
Avoid forcing exercise or trying to treat the tiredness with supplements or human medication. Let your veterinary team guide treatment once the cause is clearer.
Frequently Asked Questions
My cat is sleeping more but eating normally. Should I worry?
A normal appetite is reassuring, but it doesn’t rule out pain or illness. Check movement, grooming, thirst, litter box habits, and interest in daily activities. If the extra sleep is a clear, lasting change, arrange a veterinary check even if meals are still getting eaten.
Should I wake my cat to check on them?
When you’re concerned about responsiveness, speak softly and gently touch them. Don’t shake them or repeatedly interrupt normal sleep. A cat who barely responds, cannot stand normally, or has abnormal breathing needs urgent care. For a cat who wakes normally, observing their next usual meal or active period can be useful.
Can a sleeping position tell me whether my cat is sick?
A position alone cannot diagnose illness. Curled-up sleeping and tucked paws can be ordinary resting positions. A new, tense or hunched posture is more concerning when it comes with reluctance to move, reduced appetite, or difficulty getting comfortable. Changes in breathing require immediate attention regardless of position.
