I hope someone can give me some advice if any of you have done this.

Before I have always had a cat flap in a door but now I have a new house and
the back door is a large double glazed door which would just cost me to much
to have a flap put in. A builder friend has offered to put one in the wall
for me. Has anyone any experience of doing this? I have a couple
questions:

1. As it's a cavity wall do cats have a problem going through a tunnel?

This doesn't appear to have been discussed for several years

Yes, they will go through a tunnel, but it might need training. You
might need to keep the cat flap open for a couple of weeks while it
gets used to the concept.


In the end we had to stuff one of our into the tunnel to make it go
through the tunnel and flap.. Once she'd done it once she was fine.

We had similar thing, though ours went through two walls eventually, as
the hole to the outside was in a corner hidden by cupboards, washing
machine etc.

I lined the hole with ply - the plastic tunnel extensions seemed
expensive compared to a bit of scrap ply, with the flap on the outside
(no good though if you want a locking flap)
