Why Do Cats Like Cardboard Boxes?

Have you ever unpacked a delivery only to discover your cat is far more interested in the cardboard box than the expensive toy inside?

You’re not imagining it. For many cats, an ordinary cardboard box is far more appealing than the toy that came inside. That’s because a box allows your cat to express several natural behaviours at once – from hiding and hunting to scratching, sleeping and staying warm.

Cats like boxes because they provide security, warmth, hiding places, scratching surfaces, and opportunities to play and hunt. A simple cardboard box satisfies many of your cat’s instinctive needs, making it one of the easiest and cheapest forms of environmental enrichment you can offer.

Why do cats like cardboard boxes?

To us, a cardboard box is just packaging. To your cat, it’s a safe den, a lookout post, a hunting hide, a scratching toy, and sometimes even a comfortable bed.

Every cat is different, so your cat may enjoy boxes for one reason or several at the same time.

1. Boxes make cats feel safe

Cats naturally look for enclosed spaces where they can rest without feeling exposed. A cardboard box surrounds your cat on several sides while leaving one opening to watch the world. This creates a small refuge where they can relax knowing they don’t need to keep watch in every direction.

You’ll often notice this behaviour when:

• visitors come to the house
• loud noises occur outside
• another pet is being boisterous
• your cat simply wants uninterrupted sleep.

Even confident cats often choose a box when they want some quiet time.

2. Boxes help cats stay warm

Cats love warmth. Their normal body temperature is higher than ours, so they naturally seek out cosy places that help conserve body heat.

Cardboard is surprisingly good at insulating against cooler floors and reducing heat loss. Add a soft blanket inside, and you’ve created a warm retreat that many cats will happily spend hours sleeping in.

This is one reason boxes become especially popular during winter.

3. Boxes satisfy hunting instincts

Although your cat may never need to hunt for dinner, their instincts haven’t disappeared. Cats are ambush predators. Rather than chasing prey over long distances, they prefer to hide, watch patiently, then launch a quick surprise attack.

An empty cardboard box creates the perfect hiding place. From inside, your cat can quietly observe everything happening around them before pouncing on:

• another cat walking past
• a dangling toy
• your feet as you walk through the room
• an unsuspecting family member.

For your cat, it’s all part of the fun.

4. Boxes create the perfect observation point

Some cats don’t just sit inside boxes – they sit on top of them. Cats like having a good view of their surroundings, especially if the box is placed near a window or slightly elevated.

A sturdy box lets your cat watch family activities while still feeling protected. Stacking boxes together or placing one on a stable platform can create an even more interesting environment for adventurous climbers.

5. Cardboard is satisfying to scratch and chew

Cardboard has a texture many cats enjoy. The corrugated layers make excellent scratching surfaces that help:

• remove loose outer claw sheaths
• stretch muscles
• leave scent markings from the glands in their paws
• relieve excitement or stress.

Kittens may also chew cardboard while they’re teething or simply exploring the world with their mouths. While occasional chewing is usually harmless, excessive chewing can mean your cat needs more enrichment or alternative chew toys.

6. Boxes encourage healthy play

One of the reasons cardboard boxes never seem to lose their appeal is that there are so many ways to use them. A simple box can become:

• a hiding place
• an ambush station
• a tunnel
• a climbing platform
• a nap spot
• a puzzle toy.

You can make boxes even more interesting by:

• placing a favourite toy inside
• sprinkling a little catnip
• cutting extra doorways
• joining several boxes together with tunnels
• hiding treats for your cat to discover.

Simple changes like these provide mental stimulation without costing very much.

Why do stressed cats often hide in boxes?

If you’ve ever brought home a new cat, you may have noticed they immediately disappeared into a box or carrier. This isn’t unusual. When cats feel uncertain, hiding is one of their natural coping strategies.

Research has even found that providing hiding boxes can help cats adjust more quickly to unfamiliar environments, such as animal shelters. Having somewhere safe to retreat reduces stress and allows cats to approach new situations at their own pace.

At home, a cardboard box can offer that same sense of security during events like moving house, introducing a new pet, or having visitors stay.

Are cardboard boxes good enrichment for cats?

Absolutely. The best enrichment encourages your cat to behave like a cat. A cardboard box does exactly that, giving them opportunities to hide, observe, stalk, scratch, rest and play – all in one simple object.

A cardboard box encourages:

• exploration
• climbing
• hiding
• scratching
• hunting
• resting
• problem-solving
• independent play.

Best of all, most boxes are free. Expensive toys can certainly be worthwhile, but many cats get just as much enjoyment from a recycled delivery box.

Getting the most out of a cardboard box

A plain cardboard box is often enough to make your cat happy, but a few simple changes can make it even more engaging.

• Place the box in a quiet area where your cat already likes to rest.
• Add a soft blanket during cooler weather for extra warmth.
• Hide a favourite toy or a few treats inside to encourage exploration.
• Cut an extra doorway to create a second escape route for playful cats.
• Join two or three boxes together with tunnels to make a simple cat playground.
• Rotate old boxes with new ones every few weeks to keep them interesting.

The best enrichment doesn’t have to be expensive. Often it’s the simplest things that give your cat opportunities to hide, explore, hunt, scratch and play in ways that feel completely natural.

Are cardboard boxes safe for cats?

Most cardboard boxes are perfectly safe, provided you use a little common sense.

• Choose clean, dry boxes that are free from chemicals, staples, packing straps, or excessive tape.
• If you cut holes in the box, make them large enough that your cat can’t become stuck.
• Replace boxes once they become heavily chewed, wet, mouldy, or start falling apart.
• Supervise kittens if they’ve developed a habit of swallowing cardboard rather than simply chewing it.

Final thoughts

The next time a delivery arrives, don’t be too quick to throw the box into the recycling bin. To us it’s just cardboard. To your cat it’s a warm bed, a safe hiding place, a lookout tower, a scratching post, and the perfect hunting blind all rolled into one.

Sometimes the simplest forms of enrichment are the ones cats enjoy the most. A humble cardboard box costs nothing, encourages natural behaviour, and reminds us that good enrichment isn’t about buying more toys – it’s about giving cats opportunities to do what comes naturally.
