Circle Fat-Cat Thru-Wall Cat Tunnel

Introducing the Circle Fat-Cat Thru-Wall Cat Tunnel — a custom, 3D-printed gateway designed for larger cats who deserve their own private passage between rooms. This circle tunnel quietly threads through your wall, connecting a cat-friendly space (like a devoted cat room) to a closet or feeding area, keeping dogs and other pets at bay while giving your feline a dedicated route for play, exploration, or a quick food run.

What makes this tunnel uniquely effective

• Smart, three-piece design: Two flat circle faces and one tunnel connector assemble into a sturdy, precise pass-through that won’t sag or wobble over time.
• Size tailored for big cats: An inner hole of 7.125" and a total depth of 4.75" accommodates larger felines with comfortable headroom and body clearance.
• Wall-ready dimensions: Fits a standard wall built with 2x4s and 1/2" drywall, offering a clean, unobtrusive look that blends with typical home construction.
• Clearance and coverage: Outer hole diameter of 8.25" provides a generous opening while maintaining a neat, finished appearance on both sides of the wall.
• Color and finish options: Choose black or white for easy matching with baseboards and decor; rainbow patterns are available, though color variation is a natural result of the filament process.
• Hardware color coordination: Black and White tunnels come with color-matched screws; other colors use standard stainless steel silver screws, with the option to paint after installation for a seamless finish.
• Quality you can count on: Each unit is 3D-printed and inspected to ensure it meets our standards, with the usual small cosmetic imperfections that accompany additive manufacturing — these do not affect performance.
• Ethics and policy: STL/3D digital files are not included for sale to protect our intellectual property; we’re happy to discuss alternative shipping options if needed.

Ideal use cases

• Give a large cat a private route to a dedicated feeding area or litter box in a nearby closet or room, without inviting dogs to the space.
• Create a cat-only corridor between a cat room and other living spaces, preserving exclusivity and reducing cross-pet access.
• For multi-room apartments or homes with separate cat zones, this tunnel helps your feline navigate freely while keeping other pets out of restricted areas.

Why this tunnel matters

• Practical privacy for pets: Your cat gets a secure, undisturbed space to retreat, snack, or use the litter box without dog interference.
• Improved household harmony: By designating a cat-friendly corridor, you minimize pet frictions and accidental intrusions.
• Long-term versatility: The 3-piece assembly makes installation straightforward and future-proof if you decide to reconfigure spaces.

Tips for installation and care

• Before you install, verify the wall cavity has enough space behind the 4.75" depth and that you’re routing between rooms with appropriate access to studs.
• Handle smaller imperfections from 3D printing as normal; they won’t compromise the structural integrity or functionality of the tunnel.
• If you’re aiming for a perfectly matched look, consider painting the screws after installation to blend with your wall color.
• For color-conscious homes, note that rainbow filament prints result in varying color patterns; plan placement where variations are least noticeable.

Who this is for

• Cat owners with larger breeds who want a dedicated, cat-only passage between spaces.
• Homes with dogs or other pets where restricted access to certain areas is desirable.
• Anyone seeking a custom, wall-mounted cat tunnel that combines function with a clean, unobtrusive aesthetic.

Circle Fat-Cat Thru-Wall Cat Tunnel is a practical, purpose-built solution for modern homes that value pet comfort, privacy, and household harmony. It’s more than a passage—it’s a thoughtfully designed space that helps your cat feel secure while you maintain control over access in your home.
