Greetings -

Because our cat won't take no for an answer, we need to reinforce the
catflap against escape. The simplest solution is a slide in
'guillotine' panel which covers the whole assembly (insert jokes
about sharpened edge, baited with tuna etc).

Nah, the simplest solution is to get a different style cat flap. The
Staywell series 700 have a slide-down barrier and cost less than £10
from various on-line suppliers. At that sort of money, a DIY solution
just ain't worth the hastle.

Yes, we used to have one like that - didn't realise they were still making
them, but it solves the problem.

Brilliant - I declare this a victory for the hivemind, and thank all for
their comments!
