Are you fed up with having to climb up and down to open your door for your pet? A cat flap may be the solution. Pet-flap fitters can put them on any type of door that is available, including uPVC or composite doors. They can also install them into certain types of walls. Security It is not uncommon to see cat flaps incorporated into doors, but there are also many people who have them fitted into windows or double glazed doors. If you don't have a wooden wall or door installing one into glass is a great idea.
