Fitting a Cat Flap

Installing a cat flap your home is a fantastic step for any pet owner. No matter if your cat is older and requires extra security, or you have kittens who require a vet check, there are a lot of options there to choose from.

It can be a bit daunting for people who aren't experts in installing a cat flap, but with proper instructions, it's simple. The crucial factor is preparation, planning and precision.

Choose the Right Door, or Window

There's a wide selection of cat flaps available that come with locks (which can be used to prevent your pet going out or entering) and others that have high-tech features like microchip door entry systems. It is important to think about how it is easy to teach your cat how to use the flap before you purchase and install one.

Based on the style of your house It is recommended to situate the cat flap in the form of a door or window that opens onto a sheltered area of the garden so that your cat is secure when entering and leaving the home. If possible this will also allow them a way back should they get pursued by a different cat or by humans who are intent to harm them.

It's possible to install a cat-flap inside a uPVC or composite door, but it isn't as easy as putting one in a wood door. This is because uPVC or composite doors come in a variety of thicknesses. This can affect the how holes are cut and the type of door you can fix to.

To avoid costly mistakes It is recommended that you consult an expert glazier prior to installing the flap on a glass-fronted door. If you're installing the flap to a wooden door, you should introduce your cat to it first to ensure that it becomes familiar with its size and shape.

Measure Your Cat's Belly

You'll need your cat's measurements to ensure that the cat flap you install is a good fit. This will allow you to make sure that the flap is installed at the right height on the door or window, and also that it's large enough for him to enter and exit easily.

To do this, place your pet on their back and gently rub your fingers along their belly. Find a squishy fat pad around the lower back or face, or around the limbs. The padding provides your pet with protection and allows them to move more easily, especially when performing the many acrobatics felines are famous for.

You can also use the weight of your pet to determine the size of an opening you require. If your cat weighs at or over 5kg for instance that's a 14x12cm flap for the cat is advised.

Take a measurement of your door or window

The name implies this kind of cat flap is designed to be fixed into a door and provides an opportunity for your pet to leave or enter whenever it wants. They are typically made of plastic or aluminium and simply sit in the centre of the door with a two-way swinging door that is opened by pressing lightly on either side. The flaps can be locked which provide extra security which means that your cat can't traverse the door from outside.



Cat flaps are also often used on windows. They can be easily installed, however they have to be placed at a height where cats and dogs find it difficult to get them. If the window is too high for a cat flap then steps, ramps or purpose built stairs can be utilized to help the animal access it.

It is possible to install an egress into a brickwall, but it is not recommended for those who aren't familiar with the masonry industry. This could weaken the structure of the wall. Before you begin, it's important to ensure that the wall is free of cables and pipes. Always consult an expert when you need to cut a hole in the wall for pipes and cables. Wearing safety goggles or a dust mask will help you avoid inhaling the sawdust that is created when cutting into your walls.

Select the Right Cat Flap

There are a variety of cat flaps that are available on the market, and they all offer various features. Some flaps are equipped with security features such as microchip recognition or magnetic locks which prevent unauthorised entry. They also prevent your pet from letting guests or another animal into the house. Some seals are weatherproof and insulation to keep out draughts and moisture.

There's also a range of sizes based on the size and breed of your pet. Some cat flaps come in rectangular shapes, while others are circular or square. The kind of cat flap you select will depend on the size of the opening and the kind of door or window you're fitting it to.

Also think about the mechanism for opening your cat flap will have. A simple plastic or aluminium swing-out door is one option and is usually the cheapest. However, it will not prevent other cats or pets from entering your home and you could be letting draughts in as well.

It's time to install your cat flap. Begin by marking the belly's height on the door with a ruler. Use a spirit level to make sure the line is not too low and that it is straight across the door. Draw a template for the shape of the cat flap using your spirit level as a reference. Next, use your jigsaw to cut out the outline of the door. Once you're happy with the result, sand the edges and drill through the pencil marks to make holes for screws.

Make sure you have the tools ready

As with all DIY jobs, it's always advisable to make sure you have the appropriate tools to complete the task. You'll need the cat flap along with an eraser and tape measure as well as a spirit-level, drill, and a jigsaw, depending on the kind of door or window.

Contact the manufacturer prior to making any changes to a composite door. This could invalidate the warranty, or cause the weathertight seal damaged. In this case you'll likely have to install an entirely new pane of toughened glass instead.

For wooden or uPVC doors, you'll need to cut out the design of your cat flap using the Jigsaw. Follow the directions given by the manufacturer. Use a template to mark the size hole you require.

After you've made the hole, you must smooth the edges of the opening to smooth them. This will help prevent the possibility of water damage and rust. It is also recommended to seal the holes in your window or door and the back of the flap to keep out rain and wind. Once the sealant has dried then you can put up your new cat flap!

Install the Flap

The installation of a flap will allow your cat to go and come whenever it pleases. It's a simple procedure that most people can accomplish themselves, although you will likely need to hire an expert for installing the flap on a glass door or other kind of uPVC door.

Start by looking at  cat flap fitting  included with your cat flap to locate the template drawing. This will give an idea of the location where the holes are to be drilled to install the flap on the door. Mark the areas you'll need to drill in with a pencil.

After you have marked the door on your door, you can use the jigsaw to cut the shape for the cat flap. It is a relatively simple job, but you'll need to be comfortable using the Jigsaw. If you are concerned about doing this yourself, there are plenty of businesses that can handle this for you at a minimal cost.

The next step is to screw the inner part of the cat flap to the door's hole. You may need to seal it prior to doing this to ensure it is weather and water resistant. The outer section of your cat flap could be placed on the bolts' tops and then tightened together. It is recommended to test the flap with your cat to make sure that it works correctly and that they can get in and out of it.
