Easy to install in a solid door and quiet when working. Review: Best purchase this year - I bought this cat flap as the local unneutered tom was coming through the normal cat flap and terrorising my cat, eating his food and then spraying urine everywhere to mark his territory. He even sprayed up the radio and also at the back of my hob. That was the final straw so I went on line and found this cat flap and I can honestly say it is brilliant! It's easy to install and it takes a couple of seconds for it to read your cat's microchip. I have no more worries about another cat coming in now and my cat is a lot more chilled. It does seem a little pricey but it really is worth it for the peace of mind and not having to get up every morning and start looking and sniffing for cat urine!!! ## Features - Made of plastic material - Can be placed in thicker walls or doors - Tunnel element to be used for cat flaps - Extends the installation depth up to 50 mm - Use to install SureFlap pet doors in a wall - Multiple tunnel extenders can be stacked together - Extends the 70mm pet door tunnel by 50mm in length ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BLZOGD0 | | Batteries Included | No | | Batteries required | No | | Best Sellers Rank | 14,818 in Pet Supplies ( See Top 100 in Pet Supplies ) 74 in Doors for Dogs | | Closure | Flap. | | Customer Reviews | 4.4 4.4 out of 5 stars (2,137) | | Date First Available | 27 Feb. 2013 | | Dog Breed Size | Small | | Frame material | Plastic | | Global Trade Identification Number | 05060180390334 | | Item Form | Solid | | Item Weight | 95.2 g | | Item model number | TUN101BR | | Number of Items | 1 | | Pet Type | Cats | | Product Dimensions | 5 x 22.5 x 19.8 cm; 95.25 g | | Quantity | 1 | | Volume | 1 Kilograms | ## Product Details - **Brand:** SureFlap - **Colour:** Brown - **Material:** Plastic - **Mattress thickness:** 50 Centimeters - **Size:** S ## Images ![SureFlap Pet Door Tunnel Extender, Brown - Image 1](https://m.media-amazon.com/images/I/51Ouc2qACQL.jpg) ![SureFlap Pet Door Tunnel Extender, Brown - Image 2](https://m.media-amazon.com/images/I/61ZWctnrA5L.jpg) ![SureFlap Pet Door Tunnel Extender, Brown - Image 3](https://m.media-amazon.com/images/I/41PJ1Zcdx5L.jpg) ![SureFlap Pet Door Tunnel Extender, Brown - Image 4](https://m.media-amazon.com/images/I/41Nk3sEibPL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent cat flap *by S***N on 27 January 2025* A good value for money microchip cat flap. I have two cats attached and it works perfectly for them. Easy to install in a solid door and quiet when working. ### ⭐⭐⭐⭐⭐ Best purchase this year *by L***N on 11 May 2012* I bought this cat flap as the local unneutered tom was coming through the normal cat flap and terrorising my cat, eating his food and then spraying urine everywhere to mark his territory. He even sprayed up the radio and also at the back of my hob. That was the final straw so I went on line and found this cat flap and I can honestly say it is brilliant!

They fit together snugly to create a nice tidy tunnel. The cats love it and it's easy to keep clean. I'm only giving them four stars because 7 quid each is pretty dear for a piece of plastic! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/48050610-sureflap-pet-door-tunnel-extender-brown](https://www.desertcart.com.cy/products/48050610-sureflap-pet-door-tunnel-extender-brown) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
