This product can be used with the SureFlap Microchip Cat Door, the DualScan Microchip Cat Door or the Microchip Cat Door Connect. When mounting in glass, this accessory allows mounting in circular holes with a diameter of 212mm (min) to 260mm (max). The total diameter of the mounting adaptor is 285mm. Using the mounting adaptor for wall installations enables you to install the DualScan Microchip Cat Door more easily because you can use it to fix the cat door to the wall without the need for messy adhesives. The mounting adaptor is not required to install the Microchip Cat Door or the Microchip Cat Door Connect in a wall as these products contain wall mounting screw holes within the front frame. The Cat Door Mounting Adaptor includes two parts, one for the exterior and one for the interior of your home.

"We have had Livvy from a kitten and we have recently put in a SureFlap Cat Flap as we were having unwelcome visitors. She is much more calm and contented now thanks to this wonderful invention - thank you."

Debbie and her cat Livvy

"The boys took about 5 mins to get used to it and I can tell they're more relaxed already. Your product lives up to its claims and more."

Ian and his cats Jenson & Button

"It's very rare I write a testimonial, but I am so pleased with the SureFlap cat flap I felt the need to show my appreciation to you for bringing a sense of calm back to our cats with this wonderful invention. A product that really does do what it says on the box and is exceptional value for money!!"

Paul and his cats Oberon & Titania

"This is my second purchase of a SureFlap and I should state that the customer service provided to me both online and by telephone since my first purchase has been excellent. I have worked in the service industry for around 20 years and there are many companies that could learn a lot from the service SureFlap provides. The staff I have encountered thus far are, in my opinion, a credit to the company."

Lisa and her cats Puca & Zenith
