Have you ever bought your cat a new toy, only to find it completely ignored—while the cardboard box it came in becomes the new favorite? We've all been there.

As strange as it may seem, cats have a real fascination with boxes. But have you ever wondered why? Let's explore the science behind this quirky behavior and find out what boxes really mean to our furry friends.

Boxes Offer a Sense of Safety

One of the main reasons cats love boxes is because they provide a feeling of safety and protection. As natural predators and prey in the wild, cats seek enclosed spaces where they can hide, observe, and feel secure.

When we bring a box home, it creates a cozy little "den" for our cat. It has walls, corners, and sometimes even a lid—everything a cat needs to feel hidden from potential threats. According to a study by veterinarian Claudia Vinke, cats placed in boxes in a new shelter environment experienced less stress and adjusted faster compared to cats without boxes.

So yes, that box isn't just cardboard—it's a feline comfort zone.

Boxes Help Reduce Stress

We may not always notice it, but cats experience stress in many situations—new environments, unfamiliar guests, loud noises, or even changes in their routine. Hiding in a box is their way of coping. It gives them time to calm down and regain control.

Dr. Vinke's research confirms this: boxes can significantly lower cortisol levels (the stress hormone) in cats. When we give our cats access to hiding spaces, we help them manage their emotions and feel more at ease.

Perfect for Warmth and Comfort

Boxes also help cats stay warm. As mammals, cats have a preferred comfort temperature between 86°F and 97°F (30°C–36°C)—which is much warmer than most of our homes. The cardboard material insulates heat and helps them create a little warm bubble inside.

We often see our cats curled up tightly in boxes not just because it's snug, but because it helps them conserve body heat. A tight fit equals toasty paws!

A Hunting Advantage

Let's not forget—our cuddly cats are born hunters. In the wild, they stalk and pounce on prey, often from hiding spots. A box gives our cat that same tactical advantage. It allows them to hide, plan, and spring out like a mini lion.

This explains why our cats often wait in boxes and jump out at passing feet—or other pets. It's playful behavior, but also deeply tied to their instinctual hunting skills.

Texture, Smell, and Sound

We can't ignore the simple pleasure boxes offer in terms of sensory experience. Cardboard is soft but firm, scratchable but not too hard. It feels satisfying under their paws and claws.

Plus, boxes often carry new smells—of packaging, glue, or the outside world—which makes them interesting for a curious nose. Even the rustling sound of cardboard when scratched adds to the appeal.

So… Should We Give Them Boxes?

Absolutely! Giving our cats boxes is one of the easiest (and cheapest!) ways to keep them happy. Just make sure the box is clean, safe, and free of staples or tape. We can even get creative—cut a few holes, line it with a towel, or stack a few for fun.

Not all cats will respond the same way, of course. Some may jump in immediately, while others may take their time. But overall, providing boxes is a great way to enrich their environment.

Final Thoughts: A Simple Joy

Next time we see our cat curled up in an old shoebox or peeking out of a delivery box, let's remember—it's not just a weird habit. It's comfort, safety, play, and instinct all rolled into one square of cardboard.

Do your cats love boxes too? Have they ever ignored a fancy toy just to play in the packaging? Share your story—we'd love to hear how your furry friend makes the most out of their favorite "furniture."

Sometimes, the simplest things bring the most joy—and for our cats, that joy often comes wrapped in cardboard.
