Cat Door
There are different kinds of cat doors. Some cat doors fit right into a sliding screen door and allow the cat to run right through them. A magnetic catch holds them closed when not in use These doors require a little patience and planning to install. When you remove your screen door for installation of the pet door, Dont lose your orientation and accidently put the pet door in the top half of your screen door ! These doors are installed by placing 2 halves of the plastic pet door on either side of your screen door while the screen door is lying on the ground. Place a small block of plywood underneath the screen behind one half of the cat door and position the door half as precisely as you can so it is square. Then take the second half and gently hammer the cat door together with a rubber mallet. The door needs no screws, it stays together with a tight friction fit. Finally open the hinge flap and cut the screen away so the flap can swing freely in the door opening area. A small magnet in the flap keeps it closed when the cat door is not in use.
