Why Do Cats Love Boxes? Is This Normal?
I noticed that whenever I have an empty cardboard box lying around my home, my cat will almost immediately become curious and jump into it. No matter the size—large, medium, or small—my cat will sit, sleep, or play inside. Why do cats love boxes? Is this normal?
You have nothing to worry about—this is very common cat behavior. Cats love cardboard boxes for several reasons: they find them safe and comforting, they provide warmth, and they double as engaging entertainment.
Safety and Security
Does your cat like to sit or lounge in a cardboard box while quietly observing their surroundings? One key reason cats enjoy boxes is the sense of safety and security they offer. As Dr. Bethany Hsia, DVM and co-founder of CodaPet in Clovis, California, explains, cardboard boxes allow cats to “observe their surroundings without feeling exposed.”
This makes boxes especially helpful when welcoming a new feline friend into your home. “A cardboard box provides a safe hiding spot where the cat can retreat to when feeling overwhelmed or anxious in a brand-new environment,” says Dr. Hsia.
While cardboard boxes are beloved, they’re not the only spots cats seek for security. High-up perches—like cat trees, wall-mounted shelves, or even the top of your refrigerator—also fulfill this need.
Warmth
Some cats curl up in boxes simply because they help retain body heat. “Boxes can also serve as insulation for cats, keeping them warm in cooler or cold environments,” Dr. Hsia notes.
Cats’ average body temperature ranges from 100.5°F to 102.5°F—higher than humans’—so they naturally gravitate toward cozy, warm spots. Other favorite warm zones include sunny windowsills and soft, plush beds (yours or theirs).
Entertainment
Place a cardboard box on the floor, and you might be surprised how quickly your cat springs into action—jumping, pouncing, sniffing, and pawing at their new “toy.” That’s because boxes tap directly into cats’ innate curiosity and play drive.
“The enclosed environment of a box triggers a cat’s natural hunting behavior, curiosity, and need for a safe hiding spot,” explains Dr. Hsia. For many cats, a simple box isn’t just shelter—it’s a stage for exploration and instinctual fun.
Texture
Sometimes, it really is about how it feels. “The texture of cardboard allows them to scratch on it, which helps them maintain their claws and mark their territory,” says Dr. Hsia.
Cats are highly tactile creatures—they love exploring textures, from fluffy blankets and crisp paper to grass and tree bark. Cardboard offers just the right combination of resistance and give for scratching, kneading, and sensory engagement.
Why Do Cats Like Small Spaces?
Cats often live by the motto: “If I fits, I sits.” They’re drawn to tight, snug spaces—not just boxes, but shelves, storage bins, laundry baskets, and more.
“Cats like small spaces because it makes them feel secure and protected,” Dr. Hsia says. “Squeezing themselves into tight spaces also allows cats to conserve body heat and stay warm.”
If cluttered boxes aren’t your style, consider offering a small covered bed instead—like the Best Friends by Sheri Meow Hut Covered Cat Bed, designed with a water-resistant bottom and cozy interior for snug naps.
Are Boxes Safe for Cats?
Before handing over a cardboard box, always inspect it carefully. Remove any tape, staples, handles, or plastic packaging—these can pose choking or injury risks. Also discard loose materials like packing peanuts, shredded paper, or bubble wrap.
Pro tip: Trim sharp edges and flatten seams to create a safer, smoother surface for your cat to explore and rest in.
My Cat Doesn’t Like Boxes—Is That Normal?
Absolutely. Every cat has unique preferences. Some may dive headfirst into a new box, while others might approach cautiously—or ignore it altogether. That doesn’t mean something’s wrong; it just means your cat expresses comfort and curiosity in their own way.
