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.
