The SureFlap Microchip Pet Door from Sure Petcare is a pet door which is suitable for larger cat breeds and small dogs. It has a built-in sensor which saves and reads your pet’s existing microchip. Once saved, the SureFlap Pet Door will open only for your pet and prevents other animals from entering your home. Alternatively, it can be used with a SureFlap RFID collar tag, one of which is supplied with the product. The special double lock mechanism provides increased security against other animals. It immediately locks the pet door when it recognises an intruder trying to get in, and there is also a double lock on the inside of the house which stops pets from exiting when they are not allowed to. A further highlight is the Curfew Mode Programme which allows you to specify when the flap is locked and when it is open.
