When choosing a cat flap for glass doors, consider your pet’s habits and your home’s setup. From simple manual models to smart microchip flaps, each type offers a balance of freedom and security. Here’s a breakdown of the different types of cat flaps often used in glass doors:

Type
How it works

Tip: If you live in a multi-cat household or an area with frequent visits from stray animals, microchip cat flaps are a great choice. They allow selective entry by using RFID cat collar tags, helping ensure only your cat can come and go. If your door contains metal, check the product specifications, as metal may affect microchip reader performance.

Can a cat flap for glass doors also be installed in glass windows?

Installing a cat flap through glass windows is entirely possible. Many owners opt for this solution when space is limited or when a more discreet installation is preferred. Whether you’re installing a microchip cat flap or perhaps an innovative smart cat flap, the process is very similar to fitting a cat flap in glass doors.

Tip: If you're considering a cat flap for French doors or large glass windows, planning ahead is essential. Because most glass can’t be modified after manufacture, the glass pane typically needs to be replaced with one that has a pre-cut hole tailored to your chosen cat flap model.
