A delivery box can become much more than a place for a cat to nap. With a few careful cuts and a little rearranging, cardboard can provide hiding, stalking, scratching, climbing, foraging, and problem-solving opportunities without filling the house with another permanent toy.

Cardboard Activities for Indoor Cats: 8 Enrichment Ideas
Save to PinterestThe best cardboard activities for indoor cats are not complicated craft projects. They work because they give the cat something specific to do: follow a moving toy, search for a treat, squeeze through a tunnel, choose a route, or work their claws into corrugated material.
Before starting, remove staples, plastic labels, handles, packing tape, string, and loose adhesive. Use clean, dry cardboard without food or chemical residue, and supervise any cat that tends to tear off and swallow pieces.
1. Turn Two Boxes Into a Hunting Tunnel
A tunnel is a good use for long shipping boxes or two medium boxes placed end to end. Open both ends so the cat always has a clear exit rather than creating a closed hiding space.
Cut one or two large side openings along the tunnel. Make each opening comfortably larger than the cat’s head so there is no risk of getting stuck. Smooth any rough cut edges and remove loose cardboard fragments.
Once the cat is comfortable entering, move a familiar cat-safe wand toy outside one of the side openings so only the toy portion briefly appears inside. The changing visibility encourages stalking and pouncing without requiring a large room.
For a cat that prefers quiet exploration, skip the moving toy. Place a familiar toy just inside one entrance and allow the cat to investigate at its own pace.
Keep the tunnel on the floor. Cardboard can bend unexpectedly, so it should not be used as an elevated bridge.
2. Make a Peek-and-Pounce Box
This activity turns one sturdy box into a hunting station.
Close the top securely in a way that leaves no accessible adhesive, or invert the box so the intact base becomes the top. Cut several paw-sized openings across the upper surface and one large doorway at the side.
Put a familiar toy inside and move it between the openings from outside the box. The cat sees only brief pieces of movement, which creates a different challenge from chasing a toy across an open floor.
Keep the holes large enough that a paw moves in and out freely. Avoid tiny slots or jagged openings where a claw could catch.
For cats that become frustrated when they cannot capture a toy, periodically let the toy move out through the larger doorway where they can catch it. The activity should provide successful pounces rather than an endless tease.

3. Build an Open-Top Cardboard Maze
A maze adds decision-making to cardboard play without requiring the cat to crawl into an enclosed structure.
Use a large flat box base or a clear patch of floor. Arrange low cardboard dividers to create several wide paths, making sure the cat can step over the walls if desired. The maze should feel like an invitation rather than a trap.
Place a few pieces of the cat’s normal food allowance or favorite toys at different points. Instead of filling every passage with rewards, use only a few destinations so the cat has a reason to explore.
Start with a short, obvious route. Once the cat understands the setup, rearrange the dividers occasionally. Changing the route may make the same materials interesting again without requiring a new toy.
This is also a useful option for cats that dislike enclosed boxes but enjoy investigating objects on the floor.
4. Create a Cardboard Foraging Tray
Not every cardboard game needs a large construction. A shallow box lid can become a compact food-search activity.
Place several short, wide cardboard tubes horizontally in the tray along with a few folded cardboard dividers. Scatter part of the cat’s measured dry-food portion between and around them. The cat must sniff, reach, and move around the pieces instead of eating everything from one open surface.
Make sure every tube is wide enough that the cat cannot become stuck while investigating it. Laying tubes on their sides is safer than creating narrow upright holes that invite the cat to force its head or paw into confined spaces.
Introduce the tray with food plainly visible. As the cat becomes more confident, place some pieces slightly farther behind the dividers.
If your cat eats cardboard, skip this activity and use a purpose-made feeding toy instead. Cardboard should be explored, scratched, or moved—not consumed.
5. Lay Out a Floor-Level Cardboard Stepping Course
Cats often enjoy choosing different surfaces and routes. A low stepping course can provide that experience without creating an unstable climbing tower.
Place several sturdy boxes on the floor with generous gaps between them. Some can remain open for hiding, while others can be turned upside down to create low platforms. Keep every platform at a modest height and test each box by pressing firmly on it before allowing the cat to use it.
Add interest by placing a favorite toy on one platform or moving a toy around the outside of the course. Allow the cat to decide whether to step up, walk around, or hide inside.
Avoid tall stacks. Cardboard loses strength with wear, moisture, and repeated jumping, so an activity that was stable last week may not remain stable indefinitely.
This setup works particularly well when rearranged. Moving three or four boxes into a new floor pattern can change the route without adding more materials.
6. Make a Corrugated Cardboard Scratching Station
If a cat already enjoys scratching shipping boxes, turn that behavior into a designated activity.
Cut clean corrugated cardboard into broad strips and fit them tightly into a sturdy shallow box so the corrugated edges face upward. The pieces should be packed closely enough that they do not slide around under the cat’s paws.
A larger pad gives the cat room to stand with all four paws on the surface and stretch forward while scratching. Some cats prefer a flat pad; others may use a pad placed at a very slight angle against a stable surface.
Do not rely on loose tape where the cat can chew or pull at it. If the cardboard begins shedding large pieces or the base collapses, replace it.
Scratching preferences vary, so keep an established scratching post available rather than assuming cardboard will replace every other scratching surface.
7. Set Up a Two-Door Ambush Fort
Cats often use boxes differently when there is more than one way in and out. A two-door fort gives the cat a hiding place while still allowing movement through the structure.
Choose one large box and cut two spacious doorways on different sides. A third large opening can act as a window. Keep all openings large enough for the cat’s entire body or paw, depending on their purpose.
Rather than constantly reaching into the fort, roll a large cat-safe ball past one doorway or move a familiar toy across the outside of the box. The cat can watch from cover and choose when to emerge.
Two exits are particularly useful because the cat does not have to back out through the same opening. Place the fort where neither doorway is blocked by furniture.
If the cat simply falls asleep inside, that is fine too. The box can remain a resting space between play sessions as long as it stays clean and structurally sound.
8. Turn a Box Into a Toy-Search Station
This activity is useful when familiar toys have started to blend into the background.
Place an open box on its side and put two or three familiar cat-safe toys inside, partially hiding them behind broad pieces of folded cardboard. Leave portions of the toys visible at first.
The goal is not to bury toys deeply. The cardboard simply changes how the cat encounters objects it already knows. Reaching around a divider or discovering a toy behind a flap creates a different interaction from finding the same toy in the middle of the floor.
You can occasionally swap which toys are hidden or move the station to another room. Avoid adding every toy at once; too much clutter removes the search element.
Inspect toys before putting them into the box. Loose feathers, damaged pieces, frayed cords, or anything small enough to swallow should be removed rather than recycled into the game.

Match the Activity to the Cat
You do not need to build all eight activities. Start with the type of interaction your cat already chooses.
A cat that loves hiding under furniture may be more interested in the hunting tunnel or ambush fort. A cat that regularly bats objects under doors may prefer the peek-and-pounce box. Cats motivated by food may spend more time with the foraging tray or maze, while enthusiastic scratchers may immediately understand the corrugated scratching station.
For a cautious cat, leave a new cardboard setup in the room without trying to place the cat inside it. Familiarity can come before play.
Older cats or cats with reduced mobility may do better with open boxes, a flat scratching pad, or a wide foraging tray rather than activities that require repeated stepping or jumping. If you notice sudden reluctance to jump, difficulty moving, weakness, pain, appetite changes, bathroom changes, or another significant change in normal behavior, contact a veterinarian rather than assuming the cat simply needs a different activity.
Keep Cardboard Play Safe and Worth Repeating
Cardboard is inexpensive, but that does not make every cardboard object suitable for play. A quick inspection before each session can prevent a worn activity from becoming a problem.
Remove or avoid:
- Staples and sharp fasteners
- Plastic packing straps
- Loose packing tape and adhesive
- String, ribbon, yarn, and elastic
- Small detachable pieces
- Jagged holes or narrow openings
- Wet, moldy, greasy, or heavily soiled cardboard
- Boxes that held cleaners, chemicals, or questionable substances
- Structures that wobble, buckle, or collapse when pressed
Watch cats that chew cardboard closely. Tearing and scratching are different from repeatedly swallowing pieces. If a cat is actively consuming non-food materials, remove the activity and discuss the behavior with a veterinarian.
Rotation can also keep the setup manageable. One tunnel and one foraging activity may be more useful than six boxes permanently covering the floor. When interest fades, flatten or recycle worn cardboard and bring out a different configuration later.
Start With One Box
The easiest way to begin is to choose one sturdy box and match it to something your cat already likes doing. Cut two large openings for a hiding cat, create a shallow search tray for a food-motivated cat, or turn corrugated pieces into a broad scratching surface.
Watch how your cat uses the first setup before making the next one. Their behavior will tell you whether the cardboard is most interesting as cover, a puzzle, a surface to scratch, or an obstacle to move around. That makes the next activity easier to choose—and keeps cardboard enrichment from becoming household clutter.
