Box Contains SureFlap Cat Flap Tunnel Extender 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!!! Review: good cat flap - We are very happy with the flap and the tunnel extenders that we have bought. The flap is working well and we had no problems getting the flap to recognise our cats microchips. Recently it saved our cat from an aggresive neighbouring cat who tried to attack which was good. Ideal for cats who will not keep a collar on but still wish for only your cat to gain access to your home. Would highly recommend this flap. Not cheap but worth the money. ## Features - Warning:Not suitable for children under 3 years.

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! ## Frequently Bought Together - SureFlap Cat Flap/Door Tunnel Extender - for CAT Door NOT PET Door - SureFlap DualScan Microchip Cat Door - Door Opening is 4 3/4" H x 5 5/8" W --- ## 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.pa/products/49174302-sure-petcare-sureflap-microchip-cat-flap-tunnel-extender-compatible-sureflap](https://www.desertcart.com.pa/products/49174302-sure-petcare-sureflap-microchip-cat-flap-tunnel-extender-compatible-sureflap) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-06*
