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

Yes.


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?

Not really unless it's a very old cat.




2. The actual door seems to be on the inside leaving the tunnel exposed to
the elements (or have I got that wrong?). What's stopping it filling with
rain and allowing water to seep into the cavity wall?

Because the rain doesn't really drive in horizontally, unless you live
in Newcastle.

There are plastic tunnel liners that can be fitted together in
sections. You can glue these together with plumbers solvent weld if
you like




Knocking holes in walls is quite a drastic thing to do so I don't really
want to do it unless it really is the right thing............though I'm not
sure what else I will do if it isn't!!



It's better than using a DG door.
