Why Do Cats Sleep So Much? Uncovering Feline Sleep Patterns

Cats are famous for their long naps and endless sleep. If you’ve ever wondered why your cat sleeps so much, you’re not alone. Knowing why they rest so much can help you understand them better.

In this blog, we’ll look at why cats sleep a lot, what affects their sleep, and when you should talk to a vet. Whether you have a cat or just love them, join us to learn more about their sleepy habits.

How Many Hours a Day Does a Cat Sleep?

On average, cats sleep for around 12 to 16 hours a day. That’s like half their day spent dreaming. Some cats, especially kittens and older cats, might sleep even more, up to 20 hours a day. Their sleep is divided into short naps, which can last anywhere from a few minutes to a couple of hours. This helps them stay alert and ready to wake up quickly if needed.

Reasons Cats Sleep So Much

Here are a couple of reasons why cats love to sleep so much, so let’s go through them:

  • Natural Instincts: Cats are natural predators that need a lot of energy to hunt. Even though your indoor cat isn’t hunting for food, their instincts tell them to save energy through sleep.
  • Crepuscular Behavior: Cats are crepuscular, which means they’re most active during dawn and dusk. So, they sleep more during the day to save energy for their best hunting times.
  • Energy Conservation: Cats are great at saving energy. They often nap lightly so they can quickly jump into action if needed. It’s like they’re always on standby mode, even when they’re sleeping.
  • Temperature Regulation: Cats like to be warm, and they often look for cozy spots to sleep. Sleeping helps them regulate their body temperature, especially since they have a higher body temperature than humans.
  • Growth and Development: Kittens, in particular (just like human babies), need a lot of sleep to grow and develop. They spend most of their early days sleeping, which helps them grow into healthy adult cats.
  • Restoration and Healing: Sleep is important for rest and recovery. Cats, like all animals, need time to rest and repair their bodies because that makes them stronger and healthier.
  • Stress Reduction: Cats can get stressed out by changes in their environment or routine. Sleeping helps them deal with stress and anxiety, which gives them a safe and comforting break.

Normal Sleep Patterns

Cats have a pretty interesting sleep cycle. They have two main stages of sleep: light sleep and deep sleep. During light sleep, their muscles relax, and they’re still pretty aware of what’s happening around them. Then there’s deep sleep, where they’re completely out, so you can see them curled up tight, maybe twitching a little as they dream about chasing mice or birds.

The interesting part is that cats don’t sleep straight through like we do. Instead, they take quick naps throughout the day, adding up to about 12 to 16 hours of sleep. So, they might nap for a while, then wake up, stretch, and maybe even walk around the house before sleeping again.

This switching between light and deep sleep helps cats stay aware of what’s happening around them. Even when they’re asleep, they’re still listening for any noises that could mean danger or a chance for a snack (like the sound of treats!).

When to Be Concerned

Even though it’s normal for cats to sleep a lot, there are times when excessive sleep might be concerning. Here are some signs to watch out for:

  • Sudden Changes in Sleep Patterns: If your cat suddenly starts sleeping a lot more or a lot less than usual, it could be a sign of an underlying health issue.
  • Lethargy: If your cat seems very tired or lethargic, even when awake, it could mean there is a problem. Lethargy can be a symptom of some health issues, including infections, pain, or organ dysfunction.
  • Changes in Behavior: Pay attention to any changes in your cat’s behavior, such as decreased appetite, hiding more than usual, or avoiding interaction. These changes could indicate that something isn’t right.
  • Weight Changes: Significant weight loss or gain without a change in diet or activity level could be a sign of a health problem. Weight changes can be related to different issues, including thyroid problems or diabetes.
  • Difficulty Sleeping: If your cat has trouble sleeping, seems restless during sleep, or grooms excessively during sleep, it could be a sign of discomfort or pain. 
  • Snoring or Breathing Problems: Although some snoring is normal for cats, too much snoring or trouble breathing could be a sign of respiratory issues or other health problems.
  • Age-related Changes: As cats age, they may sleep more and become less active. However, if you notice sudden changes in sleep patterns or behavior, especially in older cats, they should be checked by a vet.

If you see any of these signs or worry about your cat’s sleep habits, it’s important to talk to a vet. They can check if there’s a health problem and suggest what to do next.


Cats love their sleep, and it’s a big part of their lives for many reasons. Sleep helps them stay healthy and happy, from conserving energy to staying alert. But even though it’s normal for cats to sleep a lot, it’s important to pay attention to any changes in their sleep patterns or behavior. If you notice anything unusual, like excessive sleepiness or changes in behavior, it’s best to talk to a vet. Remember, our cats rely on us to take care of them, so paying attention and dealing with any worries early can keep them happy and healthy for a long time.
