Cats love tight, cozy spaces — especially ones they can hide, run through, or observe from. Tunnels satisfy these instincts perfectly, offering both enrichment and comfort for indoor cats. You don’t have to spend money on store-bought versions to give your cat this joy. With a few everyday items, you can build fun, safe, and customizable cat tunnels right at home.
This guide will show you how to make effective DIY cat tunnels using materials you probably already have — with variations for kittens, adult cats, multi-cat homes, and even nervous felines who prefer subtle hideaways.
Why Cat Tunnels Are Important
Indoor cats have limited access to varied textures, hiding spots, and movement challenges. Tunnels bring variety and stimulate your cat’s natural instincts by offering:
- A sense of security and privacy
- Opportunities to pounce, chase, and play
- Gentle exercise and movement
- Safe zones for observing their environment
- Fun activities that reduce boredom or anxiety
A tunnel isn’t just a toy. It’s a mini refuge and interactive playground.
What to Consider Before Building
Before gathering supplies, think about:
Your cat’s size – The tunnel should allow easy entry and turning around Your space – Choose areas where the tunnel won’t get stepped on or blocked Cat’s behavior – Does your cat love chasing toys? Hiding? Ambushing? Adjust design accordingly Cleanliness – Use washable or easily replaceable materials Durability – Reinforce areas your cat will jump on, chew, or scratch
Once you’ve considered your setup, it’s time to choose your base materials.

You’ll be surprised how many items around the house work for tunnel-making. Here are the most useful:
- Cardboard boxes (shipping boxes, cereal boxes, shoe boxes)
- Paper bags (with handles removed)
- Pool noodles
- Towels, blankets, or old bedsheets

Add-On Enrichment Ideas
Make your DIY tunnel even more engaging with these extras:
- Hide treats or toys throughout
- Use catnip or silvervine at entry points
- Place a motion-activated toy inside the tunnel
- Include crinkly textures or bells for sensory variety
- Play with a wand toy through tunnel holes to trigger the “stalk and pounce” response
Rotate tunnel designs every few weeks to maintain novelty and avoid boredom.
Cleaning and Maintenance Tips
- Use washable linings (blankets, towels) and wash weekly
- Inspect cardboard tunnels for tears, moisture, or odors
- Replace torn paper bags often
- Store or collapse tunnels when not in use to preserve condition
A clean and well-maintained tunnel is more likely to be used consistently.
Signs Your Cat Loves Their Tunnel
If your cat:
- Sleeps in or near the tunnel
- Runs through it as part of play
- Waits to ambush toys or other pets from inside
- Rubs their cheeks on entry points
- Brings toys into it
Then your tunnel is a success!
Encouraging timid cats? Start by placing the tunnel near their favorite nap spot, then gradually move it to more open areas. Use treats and playtime to build curiosity.
