Why does my cat sit in a box that seems too small?

The tighter the fit, the more enclosed the cat feels, and the more secure. Cats that fit perfectly into a small box and then try to compress further are getting maximum enclosed-space benefit. The discomfort humans perceive in this position doesn't seem to register the same way for cats — the security payoff outweighs it.

Does giving my cat boxes actually reduce their stress?

There's research supporting this. A study published in Applied Animal Behaviour Science found that shelter cats given boxes to hide in adapted to their environment faster and showed lower stress indicators than cats without hiding spots. Giving cats boxes — or any small, enclosed hiding space — is a concrete, low-effort way to support their wellbeing.

Why does my cat sit in taped-off squares on the floor?

This is a well-documented phenomenon — many cats will sit inside a square taped on the floor even though it provides no actual enclosure. The theory is that cats respond to the visual boundary the same way they respond to a physical enclosure, treating the defined space as a 'contained' area. It works even with shapes that aren't squares.

Why Does My Cat Sit in Boxes? Security, Mostly

You spent money on a cat bed. Your cat is in the Amazon box the bed arrived in. This is one of the more reliable experiences of cat ownership, and there's a straightforward reason for it.

Enclosed spaces are genuinely calming for cats. It's not a preference quirk — it's deeply wired into what they are.

Both predator and prey

Cats occupy a somewhat unusual ecological position: they're predators, but they're also small enough to be prey for larger animals. This dual status shaped their psychology in a specific way. Open, exposed spaces are inherently stressful — everything can see you, you have to monitor all directions, there's nowhere to retreat. An enclosed space solves all of that. You can see out, nothing can approach from behind, and you can launch from cover if you decide to act.

A box is essentially perfect cat architecture. Walls on four sides, elevated visibility, and a clear exit. From inside a box, a cat can observe the room without being fully visible or exposed. It's comfortable in a way that open floor space isn't.

What the research says

A study in Applied Animal Behaviour Science found that shelter cats given boxes adapted to their new environment faster and showed lower cortisol indicators than cats without hiding spots. Hiding isn't a sign of a problem — for cats, having access to enclosed spaces is a genuine environmental need. It's one reason good cat furniture design emphasizes enclosed sleeping spots over open platforms.

The tighter the better

Cats often seem to prefer boxes that are almost too small. This makes sense from the same logic — the tighter the fit, the more enclosed it feels, and the more the walls provide tactile contact that contributes to the calming effect. It's similar to why kneading is self-soothing for cats — physical sensation and warmth are part of how they regulate stress.

Practically, the cheapest enrichment you can give a stressed or shy cat is a cardboard box. Put it somewhere elevated if you can. They will use it.
