It is crucial to ensure that the cat flap is set up correctly in order to prevent your pet from being forced through or escaping through it by other animals (e.g. dogs). It is important to measure the height of your pet's belly and the doorway of your house in order to make sure that the flap is at the correct height. If your cat is a little longer or taller than the average, you can adjust the flap's height by moving it up or down by a tiny amount.

Installing a cat flap ought to not take longer than two hours. The process can be slightly more complicated if you are required to install it in the form of a uPVC door or a composite one.

Once you've got your cat's measurements then you can examine the door to determine where to place the flap. Position the flap at the level of your cat's belly. This will allow them to go through the door with minimal effort. This will also prevent the flap from making a lot of noise as it opens and closes.
You will also need to take into consideration the thickness and structure of the uPVC door or composite. While all timber doors have the same thickness to them, uPVC or composite doors are different in their overall structure. This could make the process of fitting the flap for your cat more difficult, as you must ensure that the hole is the right size.
It is also worthwhile reading through the directions that come with the cat flap kit to locate an illustration template that can be used to mark out the location of the hole in the door. This will allow you to see where the opening must be, and also to make sure that the template is correctly positioned on the door. Using a spirit level to ensure that the template is sitting right against the door will also be extremely helpful.

Once you have determined the location where the cat flap needs to be located, mark the location on the door using a pencil. Then, if your kit comes with an outline of paper, place this over the door and use the marks to drill holes in each corner of the template. Then, you should be able cut out the template and replace it with the cat flap.
You can put in your cat flap yourself in the door made of wood or uPVC If you're comfortable with the jigsaw. Be cat flap fitting not to cut into the vertical rails or mullions of your door. You can use a jigsaw to cut your panel into a circle or square, depending on how you want it. Be patient and don't force the jigsaw to cut faster.
Once the hole has been made, carefully place the cat flap in its new place of residence. Make sure that it is firmly secured. If the flap has screw caps put them on the protruding bolts. Once the screws are in place, you can sand any rough edges of the cut then apply sealant around any gaps to ensure there aren't any draughts getting into your home.

This could have an enormous impact on the way you cut out the flap's hole and whether the flap will fit correctly after installation.
The mounting kit might include a template showing you where to drill holes. If the kit doesn't come with an example you can use a photocopier to create your own. It's important not to use the jigsaw to in order to cut, so it doesn't leave a bigger than needed hole in your door.

These can be very useful when you're worried about your pet going out at night only to come back in because of the darkness, or you're working all day. The lock can be used to allow entry or exit, and some locks can be locked in either direction which allows you to close the door completely, which is particularly beneficial for sick or elderly cats who don't want to go out in the rain.
