SureFlap Microchip Pet Door is an easy to program outdoor access solution, designed with your pet's safety in mind. It recognises your pet's existing microchip or the Sure Petcare RFID Collar Tag (1 included) to exclusively open for them, whilst preventing other animals from entering your home. The Selective entry provides your pets with increased security against other animals and helps reduce the risk of territorial stress and scent marking. Using the integrated LCD display, you can easily monitor battery levels, set your pets' entry permissions and a curfew to automatically lock the pet door at a specific time (i.e overnight).
