Introduction

Cats are often seen curled up in the sun, tucked into cozy corners, or sprawled across furniture in deep slumber. If you’re a cat parent, you’ve probably asked yourself, “how many hours do cats sleep?” The short answer: quite a lot. But there’s more to feline sleep than just long naps. In this article, we’ll explore how much cats sleep, whether cats are nocturnal, and even answer the curious question: do cats dream? Plus, we’ll explain why cats twitch in their sleep and answer another common concern—why is my cat sleeping so much?

How Many Hours Do Cats Sleep on Average?

Cats are champion sleepers. On average, cats sleep anywhere from 12 to 16 hours a day, According to the Sleep Foundation, cats typically sleep between 12 to 16 hours daily, with some sleeping up to 20 hours (Source) . Some can even snooze up to 20 hours, especially as they age. That’s more than half the day spent sleeping! This might seem excessive to humans, but for felines, it’s completely normal.

Kittens and older cats tend to sleep the most, while healthy adult cats usually clock in around 13–14 hours of daily rest. But why do cats sleep so much? The answer lies in their biology.

Why Do Cats Sleep So Much?

Cats are natural predators. In the wild, they expend a great deal of energy stalking, pouncing, and hunting prey. Even though your domestic kitty may only “hunt” a toy mouse, their instinctive need for energy conservation remains strong.

Here are some key reasons why cats sleep so much:

  • Energy conservation: Sleep helps them store up energy for sudden bursts of activity.
  • Growth and healing: Especially in kittens, deep sleep promotes physical growth and development.
  • Weather influence: Cats tend to sleep more on cold or rainy days.
  • Boredom or comfort: A well-fed, relaxed house cat may sleep more simply because they can.

If you’ve been wondering, “why is my cat sleeping so much?”—as long as your cat is otherwise healthy, eating well, and playful during their waking hours, it’s likely just part of normal feline behavior.

Are Cats Nocturnal or Crepuscular?

Many people assume cats are nocturnal because they often seem most active during the night. But in truth, cats are crepuscular—which means they’re most active during dawn and dusk.

This sleep/activity cycle aligns with their hunting instincts. In the wild, early morning and early evening are prime times to hunt small prey. Your house cat maintains this rhythm, which is why they often zoom around the house at sunrise or just before bed.

However, cats can adapt their sleep schedules based on your lifestyle. If you work a night shift or get up early, your cat may sync their active hours to match yours.

The Stages of Feline Sleep

Like humans, cats go through various stages of sleep. There are two primary phases:

1. Light Sleep (Non-REM)

This phase makes up the majority of a cat’s sleeping time. In this state:

  • Their body is relaxed but alert.
  • Ears may twitch in response to noise.
  • Cats often sleep in a loaf position—ready to jump up if needed.

2. Deep Sleep (REM)

This is where the magic happens. REM (Rapid Eye Movement) sleep is when dreaming occurs. It accounts for about 25% of a cat’s sleep time.

During this phase, you might notice your cat:

  • Twitching their paws, whiskers, or ears
  • Breathing irregularly
  • Making small vocalizations

This brings us to an intriguing question: do cats dream?

Do Cats Dream? What Science Says

Yes, cats do dream. Studies using EEG (electroencephalogram) machines have shown that cats experience brainwave activity during REM sleep similar to that of dreaming humans, PetMD confirms that cats experience REM sleep, indicating they do dream (Source , Source). During REM, a cat’s brain processes experiences and memories.

So what do cats dream about? While we can’t ask them directly, experts believe cats may dream about:

  • Chasing prey
  • Interacting with their humans
  • Playing with toys
  • Reliving daily activities

Watching your cat twitch in their sleep and wondering, “why do cats twitch in their sleep?” The answer is: it’s likely because they’re dreaming.

Why Do Cats Twitch in Their Sleep?

Twitching is a common part of REM sleep in cats, Rover.com explains that twitching during sleep is typically a normal part of a cat’s REM cycle (Source , Source). When your cat enters this deep sleep phase, their brain is active—even though their body is still. This activity often results in:

  • Whisker flicks
  • Ear movements
  • Tail swishes
  • Paw flexing or kicking

Unless accompanied by signs of distress (like vocalizing in pain or waking up disoriented), this twitching is completely normal.

How Age Affects Cat Sleep Patterns

A cat’s age can greatly influence how many hours they sleep:

  • Kittens: 16–20 hours a day. Sleep is essential for growth.
  • Adults (1–7 years): 12–16 hours, with bursts of high energy.
  • Senior Cats (7+ years): 14–20 hours. Older cats tend to slow down and rest more.

In seniors, more frequent napping might prompt owners to ask, “why is my cat sleeping so much?” Again, if your vet has ruled out illness, it’s probably just normal aging.

When Should You Worry About Cat Sleep?

While cats are naturally heavy sleepers, there are times when excessive sleep could signal an issue. Look out for these red flags:

If you notice these signs, consult your veterinarian.

  • Sleeping with eyes slightly open
  • Snoring or chirping in sleep
