Why is my cat sleeping more as the weather gets cooler?

As the weather gets colder, your cat may seem even more committed to their favourite hobby: sleeping. Longer naps, more time curled up in sunny spots, and less interest in leaving the warm blanket they’ve claimed as their own.

Cats already sleep a lot, but winter often takes it to another level. So how much extra sleep is normal, and when should you pay closer attention?

Do cats sleep more in winter?

Yes, many cats do sleep more during winter.

Cooler temperatures and shorter daylight hours can affect your cat’s activity levels, making them more likely to rest and conserve energy.

Cats naturally love warmth and comfort, so winter often means more time sleeping and less time zooming around the house.

Did you know?

Cats sleep for around 12–16 hours a day on average – and kittens, senior cats and some indoor cats may sleep even more.

Why do cats sleep more when it’s cold?

There are a few common reasons:

Conserving energy ❄️

Cats naturally conserve energy when it’s colder, especially if they’re less active during the day.

Shorter daylight hours 🌙

Less daylight can affect activity patterns and make cats more inclined to rest.

Warmth and comfort 🛋️

Sunny windows, warm beds and heated laps are hard to resist.

Age and arthritis 🐾

Older cats may sleep more if colder weather makes stiff joints or arthritis more noticeable.

Did you know?

Cats with arthritis often become quieter in winter, and signs can be subtle, like jumping less or sleeping in easier-to-reach spots.

When is extra sleep normal?

Usually, a little extra winter sleeping is completely normal if your cat is still:

• Eating normally
• Grooming themselves
• Interested in play or interaction
• Using the litter tray as usual
• Acting like themselves overall

If they’re simply choosing naps over chaos, it’s probably normal.

When should I be concerned?

It’s worth paying closer attention if your cat is:

• Sleeping much more than usual
• Less interested in food
• Hiding more often
• Avoiding jumping or movement
• Losing interest in play
• Acting withdrawn or unlike themselves

Cats are very good at hiding discomfort, so small behaviour changes can matter.

If something feels different, it’s worth speaking with your vet.

How to keep your kitty comfy in winter

✅ Do:

• Make sure they have warm, cosy sleeping spots
• Encourage gentle daily play and movement
• Watch for subtle signs of stiffness or pain
• Keep indoor enrichment up during colder days

❌ Don’t:

• Assume excessive sleeping is always normal
• Ignore changes in appetite or litter tray habits
• Let boredom build up indoors

Did you know?

A short play session before dinner can help keep indoor cats active in winter, and may even reduce those late-night zoomies.

In summary

A little extra sleep in winter is usually completely normal for cats. 😴

Colder weather, shorter days and a love of warmth all make winter the perfect season for more naps.

But if your cat seems unusually tired, withdrawn or uncomfortable, it’s worth paying attention.

Sometimes they’re just enjoying winter… and sometimes they’re trying to tell you something more.
