om...
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?

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?
Our cat tunnel had a flap on the outside to keep the weather out (kept shut
by little magnets to stop draughts,
and a lockable flap on the inside. No problems with rain, since the outer
door kep all weather out (except in real storms when there were a few drips,
but nothing to worry about.) Does mean the cost of two cat-flaps...
The tunnel was lined with hardboard, needed cleaning (muddy paws) every few
months.
The cats needed a bit of persuasion to go though at first - holding the
other door open made it less scary for them.
After a couple of weeks they were happily using it.
