1. Boxes make cats feel safe

Cats aren’t reckless animals. They’re strategists. In the wild, an enclosed space means shelter, visibility, and control.
A box:

  • Protects their back and sides
  • Reduces unexpected stimuli
  • Has one clear exit

That feeling of safety lowers stress. That’s why stressed or newly arrived cats often seek out a box straight away.

2. Cardboard retains heat

Cats love warmth. Cardboard is surprisingly good at insulating, turning a box into a cosy little mini-oven. For an animal that prefers temperatures around 30–36°C, that’s ideal.

3. Boxes are perfect hunting spots

Even if your cat sleeps all day, their hunting instinct is always on. A box isn’t just a hiding place, it’s a surprise machine. From inside a box, a cat can play, observe, and pounce without being seen.

4. It helps with stress and overstimulation

There’s even research showing that cats in shelters relax faster when they have access to boxes. Why?
Because a box:

  • Blocks out stimuli
  • Lets the cat decide when interaction happens
  • Creates a sense of control

And control equals calm. Especially for cats.

5. New things are interesting

Cats are curious, but cautiously curious. A box smells like fresh air and unfamiliar scents, and that stimulates their brain. So for cats, inspecting a box isn’t optional: it’s a duty. Simply put: a box meets everything a cat finds important.

The box always wins

Don’t throw boxes away right away. Put one in a quiet spot, or add a blanket. Chances are it’ll become your cat’s favourite place: without you having to spend a penny.

What does your cat always choose: the cat tree or the box?
