Why Are Sphynx Cats OBSESSED With Boxes and Paper Bags?

If you’ve ever ordered something online, you already know the drill: you’re excited about the package… and your Sphynx cat is already climbing into the box before you’ve even unpacked it. The delivery wasn’t for them, but don’t tell your cat that.

Boxes, bags, cardboard, crinkly paper—whatever it is, your Sphynx is absolutely enthralled. But why do these quirky, intelligent, hairless cats go wild for the most basic of objects? It turns out that there’s real science behind the behavior, and understanding can help you create a more enriching environment for your kitty.

It’s a Built-in Heat Trap!

Let’s face it: Sphynx cats are heat-seeking missiles. With no fur to insulate their delicate skin, they’re always looking for warm places to curl up. It just so happens that a cardboard box or paper bag makes an excellent heat trap.

When your cat snuggles into a small, enclosed space, their body heat gets trapped inside, turning it into a cozy little sauna. For a hairless cat, that warmth is irresistible. It’s not just comfort, it’s a survival instinct.

Want to take it up a notch? Line the box with a soft blanket or place it in a sunny corner of the house. You’ll basically never get them out of it.

It Feels Like a Safe Hideaway

Even if your Sphynx lives a life of luxury, its wild instincts haven’t gone anywhere. In nature, cats instinctively seek out small, enclosed spaces where they can hide and feel safe from predators. These hideouts also let them observe their surroundings without being seen—a crucial survival tactic.

That same instinct is alive and well in your cat. A cardboard box feels like the perfect private den. It provides emotional comfort, reduces anxiety, and gives them a sense of security.

If your cat seems stressed after a move, vet visit, or household change, try leaving a paper bag or a box out. You might be surprised how quickly they calm down once they’ve claimed it as their new retreat.

It’s Seriously Fun

Boxes aren’t just warm and safe—they’re fun! Your cat might:

• Pounce in and out like a maniac

• Hide and ambush passing feet

• Chew on the edges (Sphynx are notorious chewers!)

• Nestle inside for the perfect nap

Boxes provide sensory stimulation and keep curious kitties mentally and physically active. For such an intelligent breed, these simple enrichments go a long way toward preventing boredom.

Paper bags? Same thing—especially if they make noise. Crinkly bags trigger hunting instincts and make the whole experience more exciting.

The Science Backs It Up

Studies have shown that boxes reduce stress in cats. One study from the Netherlands found that shelter cats given access to boxes showed faster recovery times and reduced anxiety compared to those without. So it’s not just cute—it’s actually good for their mental health!

For Sphynx cats, who are more emotionally sensitive than some other breeds, a good box might be the equivalent of a spa day.

Pro Tip: Build a Box Fort or Cat Cave

If your Sphynx is showing signs of being cold or overstimulated, try:

• Keeping a few clean boxes or paper bags available at all times

• Upgrading to a cat cave or heated cat bed for added warmth

• Lining boxes with fleece or soft blankets

• Creating a rotating “box corner” where you switch out boxes to keep it novel

You can even cut entry holes in larger boxes to create multi-room hideouts or tunnels. Your cat will think they’ve won the feline lottery.

Final Thoughts

Boxes and paper bags might seem boring to us, but to your Sphynx, they’re the ultimate blend of warmth, security, and entertainment. So the next time your cat ignores the expensive toy you bought and hops into the shipping box instead—just smile. You’re doing something right.
