Cat Mate Microchip Cat Flap Wall Kit – 4 Tunnels & Wall Adaptor | Up to 270mm

The Cat Mate Microchip Cat Flap Wall Kit is a complete solution for installing a microchip-operated cat flap through brick walls, cavity walls, insulated walls and masonry openings.

This kit includes 4 × 50mm Cat Mate tunnel extensions, providing 200mm of additional tunnel length. Combined with the approximately 70mm integral tunnel supplied as part of the Cat Mate cat flap, the complete system provides a fully lined passage of approximately 270mm.

A matching Cat Mate installation adaptor is also included. This provides a larger finishing surround around the cat flap, helping to conceal the cut edges of brickwork, blockwork or masonry and create a much neater finished installation.

Everything required for a professional Cat Mate microchip cat flap wall installation has been brought together into one convenient package.

Approximately 270mm of Fully Lined Tunnel

Each Cat Mate tunnel extension adds approximately 50mm to the available installation depth.

• 4 × 50mm tunnel extensions: 200mm
• Cat flap integral tunnel: approximately 70mm
• Total available lined depth: approximately 270mm

You do not have to use all four tunnel extensions. Use only the number of sections required to suit the actual thickness of your wall.

Fully Enclosed Wall Tunnel

The Cat Mate tunnel extensions connect to the integral tunnel on the cat flap to create a smooth, enclosed passage through the wall.

This means your cat passes through a proper plastic-lined tunnel rather than coming into contact with:

• Cut brickwork
• Rough blockwork
• Cavity insulation
• Sharp masonry edges
• Internal wall materials

The result is a cleaner, safer and much more professional wall installation.

Wall Adaptor for a Neater Finish

Cutting an opening through brickwork or blockwork can leave rough and uneven edges around the cat flap opening.

The included Cat Mate installation adaptor provides a larger finishing surround around the cat flap and helps cover and conceal the cut edges of the brickwork or masonry.

This creates a cleaner finished appearance and reduces the amount of visible making-good required around the cat flap.

Microchip-Controlled Cat Access

The Cat Mate Microchip Cat Flap is designed to recognise your cat's compatible implanted microchip, allowing authorised cats to enter while helping prevent neighbouring cats and other unwanted animals from entering your home.

For cats with a compatible implanted microchip, there is no need for a conventional magnetic collar key.

Ideal for Brick, Cavity & Insulated Walls

The approximately 270mm total tunnel depth makes this kit particularly suitable for many standard external wall constructions where the cat flap's integral tunnel alone would not be long enough.

Suitable applications include:

• Brick external walls
• Blockwork walls
• Cavity walls
• Insulated cavity walls
• Timber-framed walls
• Rendered walls
• Masonry wall installations

Important Installation Information

Measure the complete finished wall thickness before ordering. The approximately 270mm maximum lined depth is based on four 50mm tunnel extensions plus approximately 70mm provided by the cat flap's integral tunnel.

Before cutting into a wall, always check for concealed electrical cables, water pipes, gas pipes, structural supports, insulation and damp-proof materials.

The tunnel should be installed level and securely supported so that the individual sections remain correctly aligned and provide a smooth passage for your cat.

Frequently Asked Questions

How thick a wall will this Cat Mate kit fit?

The four 50mm tunnel extensions provide 200mm of additional depth. Combined with the approximately 70mm integral tunnel on the cat flap, the kit provides approximately 270mm of total lined tunnel depth.

Do I have to use all four tunnel extensions?

No. Use only the number of 50mm tunnel sections required for the thickness of your wall.

What does the wall adaptor do?

The installation adaptor provides a larger finishing surround around the cat flap. It helps conceal rough or cut edges in the brickwork or masonry and gives the completed installation a much neater appearance.

Does the tunnel cover the inside of the wall opening?

Yes. The tunnel extensions connect together with the cat flap's integral tunnel to create a smooth plastic-lined passage through the wall.

Can this kit be used in a cavity wall?

Yes. The kit is particularly useful for cavity and insulated wall installations where an extended enclosed tunnel is required.

What if my wall is thicker than 270mm?

We also offer longer versions with additional 50mm Cat Mate tunnel extensions, including kits providing approximately 320mm and 370mm of total lined depth.
