Why Is My Cat Sleeping More in the Fall?

If it seems like your cat has suddenly made sleeping their full-time job now that fall has arrived, you may be onto something.

Granted, cats aren’t exactly known for their productivity.

Ellie and Jinx can turn an ordinary afternoon nap into an all-day event. Find a soft blanket, curl into a ball and apparently the rest of the day’s responsibilities have been canceled.

But when the days start getting shorter and the temperatures begin dropping, you might notice your cat sleeping even more than usual.

So, do cats actually sleep more in the fall?

They can.

Changes in daylight, temperature, household routines and activity levels can all influence your cat’s sleeping habits. But because increased sleeping can occasionally be a sign that something is wrong, it’s important to know the difference between a cat enjoying some extra fall naps and a cat that’s actually lethargic or sick.

Here’s what you should know.

Do Cats Sleep More in the Fall?

Some cats may appear to sleep more during the fall and winter months.

Cats are naturally influenced by changes in their environment, including the amount of daylight they’re exposed to.

As fall arrives, the days become shorter and nights become longer. Your cat may adjust their daily routine along with those changes.

Cooler temperatures can also make warm sleeping spots particularly appealing.

Think about it.

It’s chilly outside. There’s a soft blanket on the couch. A patch of afternoon sunshine is coming through the window.

Your cat has absolutely nowhere they need to be.

I’d probably take the nap too.

How Many Hours a Day Do Cats Normally Sleep?

Cats sleep a lot even when the seasons aren’t changing.

Most adult cats spend roughly 12 to 16 hours per day sleeping, although some cats may sleep even longer.

Kittens and senior cats often need more sleep than healthy adult cats.

And while your cat may appear to be completely asleep for much of the day, not all cat sleep is deep sleep.

Cats frequently doze lightly so they can quickly become alert if something interesting happens.

Like the sound of a treat bag opening three rooms away.

Suddenly they’re wide awake.

Funny how that works.

Why Is My Cat Sleeping More in the Fall?

There isn’t necessarily one single reason.

Several seasonal changes happen around the same time, and your cat may respond to all of them.

There Are Fewer Hours of Daylight

Cats’ bodies respond to natural light.

As the days become shorter, their daily activity and sleeping patterns can shift.

Even indoor cats may notice seasonal changes because sunlight coming through windows changes throughout the year.

Artificial lighting inside your home can reduce some of these seasonal effects, but it doesn’t necessarily eliminate them.

The House Is Cooler

Cooler temperatures make curling up somewhere warm incredibly appealing.

Your cat may spend more time sleeping:

• Under blankets
• In your bed
• On your lap
• Near a heating vent
• In a sunny window
• On warm furniture
• Next to another pet

Cats naturally seek warmth, and sleeping curled into a tight ball helps conserve body heat.

There’s Less Going on Outside

For indoor cats, windows can provide hours of entertainment.

Birds, squirrels, insects and other animals can turn a window into your cat’s personal television.

As fall progresses, some of that outdoor activity changes.

There may be fewer insects buzzing around windows and different levels of bird and wildlife activity.

If your cat has fewer things capturing their attention, sleeping may win.

Your Household Routine Has Changed

September often means a completely different routine for the entire family.

Kids return to school.

Summer vacations end.

People go back to more regular work schedules.

Suddenly, a house that was busy all summer may be quiet for several hours every day.

And what does your cat do while everyone is gone?

Probably sleep.

Your cat may simply be adjusting their schedule around the new household routine.

Does Cold Weather Make Cats Sleep More?

It can contribute.

Cats naturally look for warm places when temperatures drop.

Sleeping conserves energy, and curling up somewhere warm helps your cat maintain their body temperature.

That’s why you might suddenly find your cat spending entire afternoons buried in a blanket or stretched across the warmest patch of sunlight in the house.

Some cats also become less active when the weather is cooler.

However, a healthy cat should still wake up normally, eat, drink, groom, interact and show interest in things they usually enjoy.

Why Does My Cat Sleep in the Sun More During Fall?

Cats love warmth.

Sunlight coming through a window creates a naturally heated sleeping spot without your cat having to expend any energy.

You’ll often see cats move around the house throughout the day following patches of sunlight.

Morning sun in one room.

Afternoon sun somewhere else.

They’re basically tiny furry solar panels.

If your cat suddenly starts spending more time sleeping near windows during fall, they may simply be taking advantage of every bit of warmth they can find.

Why Does My Cat Curl Into a Ball When Sleeping?

Curling into a ball helps cats conserve body heat.

By tucking their paws underneath themselves and curling their tail around their body, they reduce the amount of surface area exposed to cooler air.

You may notice your cat sleeping stretched completely across the bed during warm summer weather but curling into a tight little ball once fall arrives.

That change can simply be their way of staying comfortable.

Do Indoor Cats Notice the Seasons Changing?

Absolutely.

Indoor cats may live in climate-controlled homes, but they aren’t completely disconnected from what’s happening outside.

They can notice changes in:

• Daylight
• Sun position
• Outdoor temperatures near windows
• Wildlife activity
• Household routines
• Heating systems turning on
• Humidity
• Sounds and smells coming from outside

Cats pay attention to their environment much more closely than we sometimes realize.

Your cat may notice fall arriving before you’ve even pulled your first sweatshirt out of the closet.

How Can I Keep My Cat Active During Fall?

If your cat spends more time sleeping during cooler months, it’s still important to encourage regular activity.

Indoor cats need opportunities to play, hunt, climb and explore regardless of the season.

Try adding several short play sessions throughout the day.

Wand toys, toy mice, balls and interactive toys can encourage your cat to chase and pounce.

Puzzle feeders can provide mental stimulation while encouraging your cat to work for food.

Cat trees and window perches also give cats opportunities to climb and observe their environment.

You don’t need to entertain your cat every waking minute.

But giving them opportunities for activity can help prevent their entire fall routine from becoming:

Sleep.

Eat.

Move to another blanket.

Sleep again.

Is My Cat Sleeping or Lethargic?

This is an important distinction.

A sleepy cat and a lethargic cat aren’t necessarily the same thing.

A healthy cat who sleeps frequently should still wake up and behave normally.

They should generally show interest in food, treats, play, attention or whatever normally motivates them.

A lethargic cat may seem unusually weak, tired or uninterested even when they’re awake.

For example, your cat sleeping for four hours and then sprinting into the kitchen because they heard the food container isn’t particularly concerning.

A cat who normally comes running for food but suddenly doesn’t want to get out of bed deserves more attention.

When Should I Worry About My Cat Sleeping More?

You know your cat’s normal routine better than anyone.

A gradual seasonal change in sleeping habits isn’t necessarily concerning.

But a sudden or dramatic change can be different.

Contact your veterinarian if increased sleeping occurs along with symptoms such as:

• Loss of appetite
• Increased or decreased thirst
• Weight loss
• Vomiting
• Diarrhea
• Difficulty breathing
• Hiding more than usual
• Weakness
• Difficulty walking or jumping
• Changes in litter box habits
• Poor grooming
• Unusual vocalization
• Irritability
• Lack of interest in favorite activities
• Difficulty waking
• Significant changes in behavior

Cats are very good at hiding illness.

Sometimes a subtle change in behavior — including sleeping significantly more than usual — is one of the first signs that something isn’t right.

If your instincts tell you your cat isn’t acting like themselves, it’s worth talking with your veterinarian.

Do Senior Cats Sleep More in the Fall?

Senior cats already tend to sleep more than younger adult cats.

Cooler weather can also affect older cats differently.

For example, cats with arthritis may become less active when temperatures drop because stiff or painful joints make movement uncomfortable.

You may notice an older cat hesitating before jumping, moving more slowly, sleeping in easier-to-access locations or avoiding stairs.

Don’t assume these changes are simply a normal part of getting older.

Your veterinarian may be able to help manage discomfort and make your senior cat more comfortable.

Make Fall a Little Cozier for Your Cat

If your cat seems determined to sleep their way through fall, give them some comfortable places to do it.

Add a few soft blankets to their favorite spots.

Move a cat bed into a sunny location.

Keep sleeping areas away from cold drafts.

And don’t forget to keep encouraging regular play and activity between naps.

Most importantly, pay attention to what’s normal for your cat.

A little extra sleeping when the weather turns chilly may simply be another part of the changing season.

But if your cat’s sleeping habits change dramatically or they’re showing other signs that something isn’t right, contact your veterinarian.

Otherwise, you may just have to accept that fall has officially arrived.

The leaves are changing.

The temperatures are dropping.

And your cat has decided they’re unavailable until spring.
