Why Do Cats Like Boxes? Safety, Warmth and Hunting

A safe place to hide

Cats are both predators and, in the wild, prey for larger animals. Being able to retreat somewhere with solid walls on most sides lets a cat rest without worrying about being surprised. VCA notes that small enclosed spaces such as boxes, drawers and sinks leave no room for anyone to sneak up on a dozing cat.

This is why so many cats head into a box the moment it is opened, and why a new or nervous cat often hides in one for the first days in a new home. Hiding is a normal way for cats to cope with change. Giving them a place to do it calmly is kinder than pulling them out.

Warm and snug

Small spaces trap heat, and cats like warmth. A cardboard box with a cat curled inside warms up quickly, and cardboard itself insulates well. VCA points out that this makes boxes cozy napping spots, which is why the same cat that ignores an expensive cat bed may sleep in its delivery box for a week.

Cats also seem to enjoy a snug fit. A box only just big enough to squeeze into, or even a square of tape on the floor, can attract a cat that wants to feel enclosed. Many cats like pressing against the sides of a box the way they might curl against another cat.

A perfect ambush spot

Cats hunt by stalking, waiting and pouncing. A box gives cover to watch from and a launchpad to spring out of, which is why cats in boxes so often bat at passing feet, toys or other pets. It turns an ordinary room into hunting territory.

You can use this. Cut a couple of paw-sized holes in a box and drag a wand toy past them, or hide a few treats inside crumpled paper in the box. These are cheap, effective ways to give an indoor cat the hunting play it needs, and they often reduce boredom-driven behaviors like night zoomies or ankle attacks.

Boxes for stressed or new cats

Because a box feels safe, it can help a cat settle into a new home, cope with visitors, or recover after a vet visit. Put an open box or a covered cat bed with a soft blanket in a quiet corner of the room where your cat spends time. Many shelters give cats a hiding box for exactly this reason.

When traveling, leave the cat carrier out at home all the time with a blanket inside, so it becomes a familiar box rather than something that only appears before a vet trip. A cat that already sleeps in its carrier is far easier to take to appointments, and less stressed when it gets there.

Keeping box play safe

Remove tape, staples, plastic wrap, string and packing materials before giving your cat a box, because swallowed string or plastic can cause a dangerous intestinal blockage. Avoid boxes that held chemicals, and check that your cat cannot get trapped in a box with a closing lid, drawers or appliances like a dryer.

Hiding is normal, but a change in hiding is not. If your cat suddenly spends most of the day in a box or under furniture, especially with a change in appetite, litter box use or energy, it can be a sign of pain or illness. Cats hide when they feel unwell, so contact your vet if your cat's hiding is new.
