The Sureflap Microchip Cat Flap is a revolutionary new idea that can prevent the same old problems associated with other flaps on the market. It was developed by a scientist and cat combination, who were fed up of unwanted visitors causing havoc in their home and also the discomfort and possible loss associated with magnetic collars. Sureflap means that your cat doesnu2019t even have to wear a collar. It will grant entry through recognising your catu2019s microchip that has been implanted by the vet. It cleverly learns the microchip with a simple one button programming and will let your cat and only your cat through the flap. Should you have more than one cat, the flap will recognise up to 32 different cats. It is compatible with the common 9,10 and 15 digit microchips.nThe aesthetic design of Sureflap means that it looks sleek, modern and elegant, as well as practical. You will find that it is easy to install on any door, window or wall. Should you want to replace an old model.
