This is the flap for the very largest cats, built sturdily based on our experience with dog doors. The flap is attached using a unique system. This makes replacing the flap incredibly easy, but… that won’t even be necessary, as this unique system prevents the flap from tearing.

- Order the cat flap in advance on our website so that it is delivered by the time the glazier comes to take the measures. The glazier will then measure both your glass pane and the cat flap. Nothing can go wrong.
- When installing the glass, the glazier will fit the cat flap, which takes only a few minutes.

The advantages
of a wooden cat flap or dog flap
Fit your cat door yourself or have it installed?
In the UK, Ireland, Belgium, the Netherlands and California (US) we have installers, so you can include the installation in your online order. We will then contact you a few days later to arrange the installation date. Very comfortable: we install with little dust and take all waste with us. Professional installation can be especially helpful when fitting a cat flap in glass doors or thicker external doors where precise cutting and sealing are required.
But to be honest, if you can make the hole in the door or wall yourself, the rest of the work is very easy. No fiddling about with small, fragile parts: only high-quality materials that are a pleasure to work with. A fun project for a handy DIYer. Many homeowners install their cat flap themselves as part of a straightforward DIY home improvement project.


Is wood suitable for a cat flap ?
Indeed, because wood gives you a lot of pleasure: it insulates, looks good, feels nice, etc.
And our wood is low-maintenance because it has been treated with oil, so that dirt cannot enter it. So if you polish the pet door a few times a year with a cloth with some oil, it will stay in excellent condition for years. Regular care helps preserve the appearance and insulation performance of your wooden cat flap.
By the way, you can also order our cat flaps ‘natural’ as well for you to finish them the way you want: do you like your cat door black, blue-grey, etc.? It’s possible! This allows the cat flap to match the colour and style of your door or interior design.
