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).

I have various types of stout thin board, that's not a problem. But I
need some J-Channel to slide it in and out of. Something
like 10-20mm wide at the back, and 5-10mm wide at the front, and
able to accept a 3-4mm board sliding in. Two lengths of 250mm would
be adequate, sturdy plastic or aluminium would be ideal.

I've seen similar stuff on the back of self assembly furniture, to
hold the hardboard back on. Common-sense says there's probably
some way to scavenge or convert it - cut-down electrical trunking,
alloy channel for fixing greehouse glass or summink?

Ideas very welcome...!

My neighbour's cat has three homes, it's own, mine and another
neighbour - depending on what mood it is in and what you feed it. It
has a collar with a magnet so when it goes near the catflap it will
open to allow it in to next door's house. Once inside it can't get
out unless the catflap is switched to allow this. The catflap can be
set for incoming, outgoing or both. It usually sits at the back or
front door here and will come in if the door is open. If it's cold
out it will sit on the window ledge ! For your catflap you need to
glue some very small trunking around the edge inside. Then slide a
piece of plastic or wood down in to it. Arrange it like a squared U
shape. Don't forget the litter tray by the door as the cat might
have a reason for going out. I wouldn't bother about it staying out, they
all come home when
they're hungry or cold, cats are very intelligent. Far brighter than
dogs.

Dogs have owners - cats have staff.
