Installing a cat flap might seem intimidating, but it is fairly simple with the right instructions. Determine how high you would like the cat flap (normally it's located at belly height). Note this on your door, and use the included template as a guide when drilling.

If you have a kitten that is still a baby and you want to keep the door open, gently prop it slightly open and allow it to pass through. Reward it each time it goes through.
Take a measurement of the door
A cat flap is a wonderful way to allow your pet to move inside and out of your house as it wants. This can help keep your cat healthy by making sure that it is exercising and also being able to go back in if it is stuck outside in bad weather, especially during the winter. This will cut down on the time you allow your cat in or out and make your home secure by letting you know when it has left.
It is essential to ensure that the cat flap is placed correctly to stop your pet from being forced through it or escaping by other animals (e.g. dogs). It is essential to measure the height of your pet's belly as well as the doorway of your house so that you can make sure that the flap is at the proper height. If your cat is a little longer or taller than the average, you can adjust the position of the flap by moving it up or down a small amount.

Fitting a cat flap should not take longer than two hours. However, the process could be a bit more difficult if you need to fit it into the door of a uPVC or composite door as these doors have various thicknesses which can affect how the holes are cut and what they are inserted into.

Once you've figured out the measurements of your cat, it is time to look at the door and decide on where to put the flap. The flap should be placed at the level of your cat's belly. This will allow them to go through the door with minimal effort. This will also stop the flap from making a lot of noise as it opens and closes.
You must consider the thickness of the uPVC or composite door as well. While all timber doors have a similar thickness, uPVC or composite doors can differ greatly in their overall structure. This could make the process of the installation of an enclosure for your cat more difficult as you have to make sure that the hole is the proper size.

This will let your cat pass through the flap with ease and make it difficult for other cats and nosy neighbours to enter or exit.
Once you've determined the best location for the cat flap to be placed, mark this position on the door with the help of a pencil. If your kit includes a template, place it over the door. Use the markings on the template to drill holes in each corner. You will then be able to cut the template's shape and replace it with your cat flap.
If you are installing your cat flap inside the form of a door made of wood or uPVC, you can do it yourself if feel confident enough to handle the Jigsaw. Be cautious not to cut into the mullions or rails that run vertically of your door. You can use a Jigsaw to cut your panel into a square or a circle, depending on how you want it. Be patient and don't force the jigsaw to cut faster.
Once the hole is cut then carefully insert the flap of cat food into its new location and make sure that it is firmly fixed. If it has screw caps, then push these onto the screws that protrude.

This can have a dramatic effect on how you cut the hole for the flap, and could affect the way your flap fits correctly once it's been put in place.

They can also be useful if you work all day. The lock can be used to allow or deny entry, and some locks can be locked in both directions, which allows you to close the door completely.
