Imagine if your cat could open and close the door as if by magic - just for itself! Trouble with strange cats coming into the house or worrying about your four-legged friend's safety could soon be a thing of the past. A cat flap with a chip is the solution: it only opens for your cat and keeps uninvited guests out.
In this article we will show you how to install a cat flap with a chip yourself, what you need to pay attention to and how to get your cat used to this modern door.
Advantages of a cat flap with chip

A cat flap with a chip offers many advantages that make life easier for you and your cat. Selective access is a major advantage: only your cat, whose chip number is stored in the flap, can go in or out. This keeps strange animals out. This is not just a question of convenience, but also of safety . You no longer have to worry about other cats or small wild animals such as raccoons or foxes entering your home unnoticed.
In addition to security, such a cat flap also offers comfort for your four-legged friend. It allows your cat to create its own daily routine without you having to constantly open and close doors. Many models also allow you to program different times for automatic opening and closing or to selectively keep certain animals inside while others can come and go freely. This can be particularly useful if you have several cats and one of them - a kitten, for example - should stay inside.
Preparation and materials for installation

Before you start installing a cat flap with a chip, it is important to have all the necessary materials and tools ready. In addition to the cat flap itself, you will need screws, wall plugs and possibly additional adapter plates, depending on the installation location. Make sure you wear safety glasses when working with tools to protect your eyes. It is also advisable to read the installation instructions thoroughly beforehand so that you are familiar with the process.
Preparing the installation site is a crucial step. Check the condition of the door or wall where the cat flap is to be installed. If it is metal, be careful of sharp edges and if it is glass, consult a specialist. You should also check local building regulations and make sure the installation site is clear of power and water pipes.
Step 1: Cutting out the opening

The first step in installing a cat flap with a chip is to cut out the opening. First, mark the size of the opening precisely on the door or wall, based on the dimensions of the cat flap. Then start sawing carefully with a jigsaw or other suitable tool. Make sure that the edges are as straight as possible.
After the opening has been sawn out, remove all chips and smooth the edges . This is important to avoid injury to the cat and to ensure a clean installation. Check that the cat flap fits perfectly in the cutout before continuing with the installation.
Step 2: Installing the cat flap

Once the opening is prepared, you can start installing the cat flap. Insert the cat flap into the opening and align it. Make sure that the flap is flush with the door or wall both inside and outside.
Attach the cat flap using the screws provided. Choose the screw length according to the thickness of the door or wall. Once the flap is securely mounted, you can put the cover caps on to hide the screws. Then check that the flap opens and closes easily.
Step 3: Program the chip and make settings

After installing the cat flap, the chip needs to be programmed. Press the programming button and bring your cat close to the flap so that its chip is recognised and stored. Most cat flaps confirm successful programming with a signal or display.
In addition to programming the chip, you can set custom settings . These include access modes such as "entry only" or "exit only" and, on some models, even time controls. Read your cat flap manual to understand all the available features and set them correctly.
Getting your cat used to the new cat flap

A new cat flap can be strange and unfamiliar to your cat at first. To get your cat used to it, you should be patient and take a step-by-step approach. Start by feeding your cat near the flap so that it develops a positive association with it. You can also play with your cat near the flap to create associations of joy and security .
Once your cat feels comfortable near the flap, you can encourage him to go through the open flap by placing treats on the other side. Here are a few helpful tips:
- Use treats : Place them strategically to lure your cat through the flap.
- Be patient : Not every cat accepts new things immediately, so give her time.
- Praise : When your cat uses the flap, don't forget to praise and reward him.
Costs and craftsmen for installation
The cost of installing a cat flap can vary and depends on several factors, such as the installation location and the type of flap. It is advisable to obtain at least two quotes from tradesmen before making a decision. Make sure that you do not pay the entire amount up front and always receive a written cost breakdown and a receipt for your payments.
If you want to install a specialised cat flap, such as one built into an external wall or glass door, it may be worth hiring a professional . A specialist will have the right knowledge and experience to carry out the job to a high standard. Check that the tradesman has public liability insurance and is a member of a professional association for additional peace of mind.

However, there are ways to make the installation reversible, for example by using a replaceable door or window panel . Here are some points to consider:
- Alternative options such as replacing the door or installing a panel solution with the cat flap.
- Consult with the landlord to find a solution that is acceptable to both parties.
- Written agreement on the conditions of installation and any dismantling obligations.
