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.

Mine has no problems going through such a tunnel, although, being a cat,
it will play the game of trying to get you to open the door just for the
sake of it

I have just 'converted' an old boiler flue into a cat tunnel by lowering
the hole a couple of bricks and lining the 'tunnel with ply. The Tunnel
is about 1 brick wide by 3 high
The Cat Flap is on the inside. The Cat manages to come through fine,
but boy does he complain that it is not as convenient as the old one in
the conservatory was!!
