The ability of your cat to come and go from the house at their own pace is a good idea to keep it physically and mentally stimulated. A flap can help reduce accidents with toilets by making it easier for your cat to leave the house when required.

Take a look at the Door

A cat flap allows your pet to go and come as they please without having to open the door for them. This makes it ideal to keep them in the house when you're home or away, and helps keep unwanted pests out of your house as well!


It is essential to measure the door before you purchase the cat flap, as there are a variety of sizes available. This ensures that you get the correct size that fits into your upvc door, otherwise, it might be too small or too large for your cat and he will struggle to use it.

Take a ruler, and determine the width at several places along the edges of the door. Also, you should take measurements of the door's height in a few places. A door that is too tall will make your cat do an acrobatics routine each time it is tempted to use the flap.

If you're not sure how to measure the door, it may be best to ask for help from a glazier or someone who is familiar with this type of work frequently. They should be able to assist you in determining whether or your door is suitable for a cat flap and help you decide on the best size of flap to buy.

Once you've got your measurements, the next thing to do is to draw out the shape of the hole on the door. This will provide you with a guide when it comes to cutting the hole and will prevent you from making an error that will cost you money in the future!

It is also important to ensure that the hole you're creating is placed in the right spot. If you are fitting a cat flap to an outdoor door, it's crucial that the hole doesn't get too close to the hinges. This could result in leakage or problems with the seal.

It is recommended to leave the task of installing a cat flap on a glass door to a professional glazier. It can be very tricky to install a cat flap into an existing glass pane, and you may be surprised to find that the process causes it to break and lose its weatherproof seal.

Measure the Cat

A cat flap permits your pet to move around as they please without you having to leave them home to themselves. It also helps keep draughts out of your house, which aren't good for either you or your cat!

If you have a uPVC door or composite door, it could be difficult to install a cat flap. These kinds of doors are often made with different materials than standard wooden or uPVC doors and the procedure for installing them is different as well. Make sure you check with the manufacturer if it is compatible prior to installing the cat flap on your uPVC composite or uPVC door. Modifications can invalidate warranties.

They are designed to last and are tough, with insulation. They are more resistant to weather than other types of doors, however it isn't always easy to install a cat flap. If you're unsure about whether your uPVC or composite door can accommodate the cat flap, make sure you consult with a professional joiner before starting.

To ensure that your cat can pass through the door, you'll have to take a measurement of their height. It's easier to measure their height when they are calm or asleep, so they aren't moving around. Once you have their height, you can measure the distance between their stomachs and the floor in order to determine the position of the flap's bottom. This position is marked on the door.

If you are using power tools to cut your composite or uPVC door, you need be cautious. Drilling into metal can cause it crack, especially when the area is made of toughened glass. It is recommended to hire an expert glass installer when putting in the cat flap inside the pane. This will stop the glass from breaking and becoming hard. A glazier will also be capable of providing you with a circular cat flap hole that is less likely to break and is safer for your cat to use.

Cut cat flap cover for winter should come with a template that you can use to mark the area on your door where the hole will go. If it doesn't, you can create your own by using a thin sheet of paper (tracing papers are great). After the shape is drawn in pencil on the door you can then use your spirit level to make sure that the shape is completely horizontal. This will ensure that the cat flap is positioned correctly in the opening, and it will not open or close.

Then, you can use your jigsaw, and cut the design that was drawn on the door. Make sure you are using a blade that is suitable for use on uPVC doors - usually it will be marked as such If not, ask the staff at your DIY store for advice. Once the hole is cut then place the flap against it and open it to ensure that the flap moves easily. If it is bound on any points then use a file or rasp to correct this.

Check that there aren't any gas or electric pipes inside the door you plan to cut through. Your jigsaw could cause damage to them. You should also be aware of any handles, or other fixtures that are in the door, which must be removed to fit the cat flap. Be cautious not to damage these items while cutting.

Most people who install a cat flap on their own will have the standard solid uPVC front door, which means they won't have to deal with these problems. If your door is constructed of timber or has a decorative panel that cannot be removed, this could increase the difficulty of the job.

It is always advisable to seek professional assistance from a cat flap fitter for these kind of jobs since it is essential to do the job done correctly to avoid potential issues in the future. Getting it wrong can result in the door becoming damaged, which could cause the warranty to be invalidated.

Place the Flap

Once you've got the hole drilled, place the flap on to check if it fits and opens easily. If you find any points that stick or catch or stick, you can file them down using an sandpaper or hand file until it fits properly and opens without any problems. Make sure the flap is in a flush position with the door.

Some kits include a template for this however, even if yours does not provide a template, you could use a piece or thin paper instead - something similar to tracing paper. Place the paper on the door, and draw a line to indicate the location where the flap is placed (this will serve as a cutting guide). Then using the pencil lines you've drawn on the door, draw four screw holes in the corners of the flap - these will be the screws that you'll use to secure it in the correct position.

Most uPVC doors are strong and therefore quite straightforward to cut into. If your door is constructed of GRP or composite the process can be more difficult. If you are not familiar with this, it is recommended that you hire an expert. They will also be able to help you determine whether or not your door is suitable for installation of a cat flap.

If you're planning to install a cat flap on composite doors, it is essential to first confirm the manufacturer or a professional joiner. Any modifications made to these doors could make it impossible to honor the warranty. If you choose to complete the task yourself, be aware that this could be a messy and potentially dangerous job.

With composite doors, you'll generally require a saw or grinder to cut through the door panel itself instead of just cutting through the GRP. This is a risky job, and you will have to be extra careful to avoid damaging the door. It's important to remember that cutting holes into any type of door glass is far more difficult than making the same modification in the case of a uPVC or solid timber door.
