Cat flap in a wooden door

uPVC and wooden doors

Measure the height of your pet’s stomach off the floor. Mark the height of your pet’s stomach on your door. This will be where you will place the bottom of the inside of the pet door, so your pet can walk through the pet door comfortably. If you have more than one pet that will be using the microchip pet flap, make sure that the smallest measurement from your pets’ stomachs to the floor is used. Make this mark where you want the centre of the microchip pet door to be, horizontally. Also mark this on the inside frame of the cat flap.

Using this mark on the door as the centre of the inside bottom face of the pet flap, fix the cat flap frame to the door with tape or Blu Tac. Then draw the inside line of the cat flap frame on the door. The idea is to match up the centre mark on the door with the centre mark on the cat flap frame. It would help to use a spirit level to check whether the microchip cat door is to be level. Mark where the drill holes for the microchip cat flap frame are to go.

Making a hole in a wooden door for a cat flap

With a large drill bit, make holes in the corner of the outline. These holes need to be large enough to fit a jigsaw drill into. It is recommended to drill from both sides to avoid splintering. Take care to make sure that the holes will line up. To do this make sure that you have outlines drawn on both sides of the door that line up.

Then cut the outline out with the jigsaw drill carefully. Drill the holes for the microchip cat flap screws. The size of the holes will depend on which microchip cat flap you buy. Screw the microchip pet flap into place and make sure that the frame with the buttons is on the inside. Use a hand screw driver as opposed to a power screw driver to prevent over tightening the screws.

Your microchip cat flap should now be completely installed, but that will depend on which microchip pet flap you have.

Cat Flap Installation in Glass Door

Each cat flap installation in glass will have slightly different ways, as they differ between brands and products. There are, however, similarities between them all though. First, you should set up the microchip pet door for your pets. This can be done after installation but is best done beforehand. See here for how to set up for your microchip cat flap.

If you do not feel comfortable to follow the advice here to install a cat flap in glass or the manufacturer’s instructions, then click here to find a cat flap fitter in your local area for pet door installation.

Put simply, cut a hole into your wall, door or window. Then the microchip pet flap can be fixed around it. For step by step instructions on pet door installation into a glass door or window, see below.

Cat flap installation in glass door or window

For a microchip cat flap in a glass, such as a double glazed door or glass window, a professional glazier or pet flap fitter will be required to cut a circular hole in the glass. The size of this hole will vary depending on the size of your microchip pet door. A single pane of non-toughened glass could probably be cut in-situ, or in its place, by a professional cat flap fitter. However, a double glazed window or door would have to be removed for cutting.

You must tell your professional glazier or pet door fitter that a non-metallic spacer bar should be used in double glazed glass. Any metal in the glass would reduce the range, and effectiveness, of the microchip cat door.

Measure the height of your pet’s stomach on your door. If you have more than one pet that will be using the microchip pet flap, make sure that the smallest measurement from your pets’ stomachs to the floor is used. As there is a circular hole in the glass, add 12cm or five inches to the height between your pet’s stomach and the floor. Use this value for the centre of the circle off the floor. If the microchip cat flap you have bought does not provide any instructions on this.

Mounting adapters

This should be at 20cm or eight inches off the bottom of the glass to allow room for the mounting adaptor. For most microchip pet doors in glass windows and doors need a mounting adaptor. There will be a mounting adaptor for both sides of the glass. Place a bead of all weather sealant around the two mounting adapters.

Place one of the mounting adaptors, with the sealant, with the inside part of the microchip cat flap placed through the hole first. Then the outside mounting adapter and outside frame of the microchip cat door. It would help if you had somebody to help you on the other side of the door for this part.

Also make sure the sealant is on the glass side and use a hand screw driver. Don’t use a power screw driver, for the screws to make sure you don’t over tighten them.
