Cat flaps

[Froggy]

Has anyone ever made a cat flap from wood. A friend has had a house built and wants to put a cat flap in the door, but the only size he can buy is too big for the space he has on the door. So I thought I might be able to make him one to size in wood. Anyone point me in the direction of some plans please?

I have a job coming up where I have to supply a hardwood door with a custom made dog flap suitable for 3 large German Sheppards.

I plan on using a quality exterior ply and rare earth magnets

I use a dowel, two u shaped clamps and a piece of 3mm ply with two rare earth magnets to hold it closed,
The wind can set up a resonance with the flap and magnets so that it goes wip wip wip wip wip.... for ever

I tried adding brushes for windproofing but just cat proofed it

the brushes and empty brush mounts are a failed attempt to make it more energy efficient in winter. The magnets are a couple of geomag magnets
