Is your cat acting like it is auditioning for the role of sleeping beauty? On average, cats often clock in 12 - 16 hours of nap time daily, with kittens pushing this snooze time to 20 hours. However, each cat is a unique blend of fur and saas. So, if your kitty has upgraded its sleep schedule along with some other symptoms keep a closer look.
There are 10 significant reasons why your cat might be sleeping too much. Most of them are due to latent health conditions. Other than that, seasonal changes, dietary imbalances, and boredom are significant reasons for cats to take too many naps.
In this article, we will discuss those 10 reasons in detail.
Here's is an infographic that you need to know about a cats’s sleeping habits and when to worry about them.

10 Reasons Why Your Cat is Sleeping More than Usual
While often we are appalled by the places and positions cats are sleeping, too much napping or a drastic change in sleeping behavior might be a sign of a severe medical condition. In general, a cat might sleep too much due to the following factors:
- Seasonal Changes
- Thyroid Imbalance (Hypothyroidism)
- Chronic Pain
- Cognitive Dysfunction Syndrome (CDS)
- Dietary Imbalance
- Parasite Infestation
- Boredom or Environmental Stimulation
- Low Blood Sugar (Hypoglycemia)
- Side Effects of Medications
- Undiagnosed Neurological Issues
Let’s elaborate on these factors.
1. Seasonal Changes
Despite hundreds of years of evolution, cats still retain some of the instincts of their ancestors. They would hunt less frequently in colder weather to conserve energy and reserve fat, especially in the winter. Therefore, it is very common for cats to sleep more during October to February.
Reduced daylight hours can influence your cat’s sleep cycle, making them find warm spots and curl up to take some Zs. Additionally, if you have adjusted your sleeping routine, your cat might also adapt to that. They will want to play outdoors less, climb on the top of your heater, and take a nap.
2. Thyroid Imbalance (Hypothyroidism)
The lack of thyroid hormone, thyroxine, in your pet cat’s system, can cause your cat to take more naps than ever. This hormone controls your pet's metabolic rate, meaning it regulates how quickly the body burns up energy. This condition can also impact the following organs and systems in your cat’s body:
- Heart
- Skin
- Body temperature and weight
- Infection fighting
- Brain and nervous system
- Energy levels
Hypothyroidism is a lifelong condition in cats. It is very challenging to detect in the early stages as this condition mimics other health conditions that worsen over time. If your cat is showing different health conditions related to low thyroid hormone, take it to a vet immediately. While there are no permanent remedies for this condition, you can manage the symptoms with the help of your vet.
3. Chronic Pain
Instinctively, cats are very stoic pets who don’t like to show any sign of physical weakness. However, various health conditions like arthritis, dental diseases, neurological conditions, infections, and even inflammatory conditions can cause chronic pain in cats. When your pet is suffering from any of those conditions, it might take very frequent snoozes.
If your pet projects this sign along with personality changes, litter box behavior changes, and a tendency to sleep in lower places than usual, get your furry friend checked immediately for chronic pain.
4. Cognitive Dysfunction Syndrome (CDS)
Aging can significantly impact your cat’s sleeping behavior. Older cats can develop CDS, which is similar to dementia that changes the sleep-wake cycle in your pet. Due to this condition, your pet will sleep more during the day and become active at night.
This situation might occur due to your cat being confused, anxious, or suffering neurological decline associated with CDS. In addition, your cat might get lost in familiar places, forget litter box training, decrease grooming, or show changes in appetite. If you discover these signs, make sure to schedule a veterinarian visit as soon as possible.
5. Dietary Imbalance
If your cat lacks the necessary nutrients in their meals, it will also impact its sleeping behavior. A diet consisting of excess carbohydrates can cause obesity in cats and cause fatigue in those cute four-legged entities.
If you see your cat is gaining too much weight, make sure to change its diet accordingly. If you are struggling to find out if your pet is overweight or not, take a look at our checklist.
6. Parasite Infestation
Your cat’s sleeping pattern is directly related to its energy levels. However, if your energetic cat is sleeping too much lately, there is a chance it is suffering from parasite infestation. Parasites like heartworms or intestinal worms can sap your pet's energy levels. This can severely impact your friend’s health.
If you anticipate that your cat is suffering from viral infections or bacterial infections, immediately pay a visit to your vet for investigation. The sooner your cat is diagnosed, the earlier you can start the treatment.
7. Boredom or Environmental Stimulation

Like humans, cats can also get bored and even develop depression symptoms. Oversleeping is often a glaring symptom of this occurrence, accompanied by loss of appetite, avoidance, and other unusual behavior.
Kittens as well as older felines, may develop this due to underlying illness. The best thing to do in this situation is to take your pet to a vet. To help your cat get out of boredom, you can also give it interactive toys and puzzles to play with.
8. Low Blood Sugar (Hypoglycemia)
Hypoglycemia or Diabetes is a common illness that occurs in felines. This causes an imbalance of blood sugar or glucose levels in the blood. As a result, your pet might show symptoms like lethargy, weight loss, vomiting, and dehydration on top of sleeping too much.
This can be regulated by insulin therapy recommended by a professional veterinarian. Some cats might need a combination of insulin therapy and medications. Also, you will have to maintain a strict diet and feeding schedule for your beloved pet.
Remember, the earlier your cat is diagnosed and treated for Diabetes, the better quality of life it can lead. With proper treatment, your cat may even enter a state of remission. However, even if your pet is in remission, you need to keep a close eye on it to make sure the chronic condition does not come back.
9. Medication Side Effects
If your cat is already medicated due to health conditions, it might sleep more than before due to the side of the medications. This is especially true for allergies, anxiety, or pain medications.
In such cases, you need not be concerned if you are following your vet's proper guidelines. Let your cat take as many naps as it wants and get better.
10. Undiagnosed Neurological Issues
Last but not least, cats can often develop a list of neurological issues. However, being stoic animals, cats are very good at hiding their weaknesses. So, it is natural for some neurological issues to be undiagnosed.
Any problems that affect the brain or nervous system of your cat like brain tumors, seizures, or inflammation can cause lethargy or prolonged sleep cycle for your cat.
Here is how a cat usually sleeps. In the picture, you will have a clear idea about it.

Final Words
It is not uncommon for a cat to take multiple naps and snooze in a day. However, if you are concerned about the unusual routine associated with more abnormal behavior, make sure to pay your veterinarian a visit.
Each cat has different personalities and temperaments. Therefore, their sleeping habits will also vary significantly. So, as a pet parent, you should be able to detect if your pet is behaving out of its normal traits. If you see any such unusual behavior, make sure to take immediate action for your pet’s overall well-being.
It is often possible for cats to get lost while finding a suitable napping spot. In such cases, you can easily use PawMaw’s huge pet community to look for your pet and get it back home as soon as possible.

Herpes gone!!!…..
My cat is an indoor cat, the vets have been messing me around with finding out what she is allergic to for nearly a year and I have no idea if it is food or environment. She has to wear a cone or hood a lot as if unsupervised she will just bite and lick at her legs, making open wounds. She has been just laying around and sleeping a lot. She tends not to move for hours and hours on end. Her eating has always been an issue as she is stupidly fussy for a cat. But her pooping has become a big issue and she has had to have a micro enema just yesterday. But the vet thinks it could be due to her not being active but I\'m really struggling to get her active as shes so uninterested. I think removing the cone will probably help, but I have no way to stop her biting at her legs- shes done an elimination diet, that yeilded no results, she had steroids, she had extra omega 3 to strengthen her skin barrier. Shes even on prozac to try and stop her compulsive grooming. Literally nothing is working and I keep wondering if I need to surrender her to a shelter who can work with her and get her better.

my 3 cats slept 21 hours a day and they are all 4 years old. I don\'t know what is wrong with them.
My cat Sam is only 3 years old and sleeping a lot? He isn\'t sick because he runs and play and eats? He doesn\'t act like he is in any pain? He is a indoor cat doesn\'t ever go outside. And he\'s going to the bathroom without a problem? It is winter were I live?
My 10 year old cat hasn\'t urinated or had bowel movement since yesterday. She is still eating and drinking. She usually goes out first thing in the morning. Today she is sleeping and not using her litter box. Not interested in going out
My cat cannot get up into my bed because it’s too high for her. (I have a loft) She is overweight, but she’s not HUGE. She’s around 13 pounds. My cousin put her up in my bed around 4 am, and it is now almost 10 pm. She has been up there for almost 18 hours!!!!!! She can get down, but she doesn’t want to. It could be have to do with boredom since there is a dog over currently and she doesn’t want to be around it. She hangs out in my room for most of the day because of the dog and people. The weather has been sorta humid and drizzles a little here and there. She is only 2 years old, and I don’t think she has diabetes at all. She loves her food. I just can’t believe how long she has been sleeping for!
My cat had a seperation from my partner and became physically unwell, which he overcame. He is now sleeping all day and night, and is sleeping with me, sitting very close to me and letting me belly rub him. He would never do this when my partner was here. I couldn\'t even pet him. Do you think he is depressed? He\'s eating but not playing, which he loves as he\'s an indoor.
Becca, I am not expert at all, but it sounds like your cat really misses your partner. It almost seems like they are grieving. Your cat could be depressed... :C I hope your cats spirits are lifted soon. I will pray for him.
I own a kitten named Luna. She\'s 5 months old. I believe she has an eye infection in both eyes. It\'s not that serious but I noticed her eyes are pinky/red. She slept a lot today and seems to be alright. Can someone please tell me what I should do? \r\nThanks
Pretty Kitty, when in doubt take her to the vet
My 3 cats, Mr. Snug, Little Buddy and Baby Girl are sleeping a lot more than usual. It is rainy and cold outside, however, they are indoor cats and always warm and dry, so would they still be affected by the weather?
I was wondering if someone could help me my kitten kikyo which is around eight or nine months had recently gotten pinkeye and transferred it to her other eye we took her to the vet and they told us that the only thing that was wrong with her and that she’s completely healthy other than that but why is she sleeping so much can anyone tell me?
Khaliah, kittens sleep up to 20 hours a day! The pink eye can be treated with warm compress and a vet might prescribe and ointment or eye drop if you are able to take your kitten to the vet!
My cat is so lethargic, I have had him to the vets, he has had xrays and blood test but nothing has been found, I have already spent 11 hundred pounds and I am now frightened that if he was to have a referral they may find cancer. I am puzzled to what to do.
One of my cats started sleeping the whole day some days ago and now she is in the verge of dying, she\'s neither eating nor drinking water and now she can\'t even stand up. There\'s no vet around me. I tried to feed her but she vomits it each time and now she does not even open her mouth accept for crying. She\'s more than 2months old.\r\n\r\nNow, my other cat is also sleeping very much suddenly today. Is the same thing happening with her also?
My kitten is only 9 weeks old and usually plays and zooms around all the time however today he hasn’t run around or played at all just slept all day and seems a little unhappy I have felt his nose and it’s a little dry he hasn’t eaten too much but has eaten a little but does drink milk all the time is there anything I should be concerned about
Natasha, Don\'t ever feed cats cow\'s milk!
Natasha, cats should never have milk. Cats are lactose intolerant and the indigestible lactose in its gut will ferment, causing a stomach upset, diarrhea, and pain. Milk can seriously imbalance their diet causing nutrient deficiencies as well. No matter how much they love it, don\'t give any kind of milk to your fur-babies.
I was on vacation for a week. I had my neighbor come in daily to feed my two 9 year old cats. It\'s been three days since I\'ve been home and my male cat seems to be sleeping much more than usual. Otherwise his appetite is o.k. but his playfulness has dropped off too. Should I be concerned?
My cat is normally 1st out the door in the morning but last 4 days he is not bothered & sleeping more than usual please advice he still eats & drinks
My cat sleeps all day. But she will get up about 3 times a day for her treat. She eats mostly at night. She’s just nibbles! It takes her more then 6 months to finish a 15 lb bag of food. \r\nShe does play at night at times but not often. \r\nShe is 6 or 7 and a calico cat.
My cat has slept all day and has never done that before what is going on????
I have 3 cats,Precious age 9,Smokey, age 7, and Scarlet age 2 and Scarlet likes to aggravate Smokey so much that when Scarlet isn\'t bullying her Smokey sleeps a lot during the day and night ... I\'m thinking Smokey is stress out and that is why she sleeps a lot. Any advice?
Brenda Lane, I bought my cats feliway. It helps stress a lot.
My cat she seems sleep a lot. I love my kitty very much.
My 2 cats often sleep not their usual behavior, they have difficulty in standing and lose their appetites but they drink milk. I\'m worried about them, please advice me what should I do. Thank you.
Cows milk will make cats sick.
Cows Milk is very bad for cats
AC, I say you should take him/her to the vet
My cat is 15 months old. She’s been in the house for 3 days. Today, she has been sleeping non-stop. She seems lethargic, and wobbly. I didn’t notice her behavior until tonight. Not sure what’s going with her. Definitely not her normal behavior.
Marilyn, that is exactly what has been happening to my cat
My cat sleep all the time
Hi my male cat is about 7 years old and today I saw he got a round red area on his stomach and he seems to be sleeping more then he does and he keeps cleaning it alot and he is not eating alot
Sam, I would take him into the vet to get looked at...Is the red area a lump? Or is it from your cat licking himself/herself raw? My cat did that in the past because she was in pain. There is probably something wrong with your cat internally. Mine had some intestine issues, but she licked a patch on her paw raw.
One of my cats has been sleeping a lot more then usually which is not normal for him what should I do to help him
My cat is sleeping since last night what is going on.
Helga augustin, same
Helga augustin, is he ok
For the past few days my barn cat has been inside sleeping for like three hours straight since yesterday. What’s going with on?
