Measure the Cat

A cat flap allows your pet to leave and come back whenever they want, without having to leave him on his own. It can also prevent draughts entering your home, which isn't healthy for you or your cat.

If you own a uPVC door or composite, it may be difficult to install the cat flap. These doors are constructed of different materials and the process of installing them is different. Make sure you check with the manufacturer to see if it is compatible prior to installing the cat flap on your uPVC composite or uPVC door. Alterations may invalidate warranties.



These doors are typically designed to be tough and durable, with insulation. This makes them more resistant to weather elements than other types of doors, but they can be a challenge to insert the cat flap. If you're unsure about whether your uPVC or composite door is able to accommodate a cat flap, check with a professional joiner prior to beginning.

To ensure that your cat is able to get through the door, you'll have to determine their height. It is easiest to measure their height when they are calm or asleep, so that they aren't moving around. Once you've established their height, measure the distance between their stomachs and the floor to determine where the bottom of the cat flap needs to go. This position can be outlined on the door.

When using power tools to cut your uPVC door or composite door, you will need be cautious. Cutting into metal can cause it crack, especially when the area is composed of toughened glass. This is the reason it's recommended to engage a glazier when installing your cat flap in the glass pane. This will prevent the glass from breaking or becoming fragile. A glazier can also supply you with a circular hole to use for the cat flap, which will be less likely to break and is more secure for your cat to use.

Cut the Hole

A good cat flap will come with a template drawing that you can use to mark the location on your door where the hole will go. If it does not then you can create one by using a sheet of thin paper (tracing paper is the best choice). Once the shape has been drawn in pencil on the door, you can then use your spirit level to make sure that the shape is horizontal. This will ensure that the cat flap is positioned correctly in the opening and will not open or close.

Then, you can employ a jigsaw for cutting out the design that is on the door. Make sure that you're using a blade that is suitable for use on uPVC doors - usually it will be labelled accordingly If not, ask the staff at your DIY store for advice. Once you have the hole drilled then place the flap up against it and push it open to ensure that the flap's movement is smooth. If it is bound on any points then make use of a file or a rasp to fix this.

Make sure there aren't any electric or gas pipes in the door you're going to cut through. Your jigsaw could damage them. Similarly you should be aware of any handles or other fixtures on the door that need to be removed in order to install the cat flap. Be careful not to damage them in the process.

The majority of people who install a cat flap themselves will have an ordinary solid uPVC door and will not have to worry about any of these problems. If your door is made of timber or has an ornamental panel that can't be removed then this will make it more difficult to complete the job.

For these kinds of jobs, it's recommended to seek out expert advice from a cat-flap fitter. It is crucial to perform them correctly to avoid future problems. Making the wrong choice could result in the door becoming damaged and may cause the warranty to be invalidated.

Install the Flap

Once you have cut your hole, you can place the flap to see if it opens and is able to fit. If you find any points that stick or catch, file them down with the aid of a hand file or sandpaper until it fits correctly and opens without any problems. Make sure that the flap is in line with the door.

If your kit doesn't include templates, you can use tracing paper that is thin, such as a piece of paper or Acetate. Lay the paper against the door and mark an area on which you'll will need to place the flap (this will be your cutting guide). Then, using the pencil lines you've drawn on the door, mark out four screw holes in the corners of the flap - these will be the screw points you'll use to fit it in the correct position.

The majority of uPVC doors are solid and therefore quite straightforward to cut into. If your door is made of GRP or composite however, it could be more difficult. If you're not comfortable with this, it's best to hire a professional. They will also be able to determine if your door is suitable for the installation of a cat flap.

If you are planning to install a cat flap on composite doors, it is essential to first check with the manufacturer or a professional joiner. Any modifications made to these doors may make it impossible to honor the warranty. If you decide to do the work yourself, be aware that it can be messy and possibly hazardous task.

You'll require a saw or grinder to cut through composite doors, rather than only the GRP. This is a potentially dangerous job, and you'll have to be extra careful to ensure that the door is not damaged. It's also worth noting that cutting a hole in any type of door glass is much more difficult than making the same modification in a uPVC or solid wood door.
