I'm wondering about a reduced length window in the centre section
and if possible, a new crosspiece to enable secure glazing and
place to put a cat flap. Is this possible post-manufacture?

You could probably get a custom replacement sealed unit made up with a
suitable hole for the flap in it. Then just swap out the whole pane.

The only way I've seen this done is by replacing the lower glazing panel
with something else, looks like some kind of hard plastic on the one I
remember. Then a cat flap was fitted.

In this particular case that is not so easy as the photo shows a door
divided into three full height vertical glass panels. It would be tricky
to fit in a new cross member and not have it look a bit odd.

In our case we put the cat-flap through the wall next to the uPVC door.
The flap itself is on the inside, the other side of it there's a tunnel
to the outside. Cats seem to cope well with that.

+1 did the same here... just fitted the external bezel on the outer wall
and made up a WBP ply tunnel to link the flap and exterior bezel.

No need for a ply tunnel. You just needed one of those proper drills,
like they used on the Covent Garden safe deposit raid. A big Hilti IIRC.

Technically I expect it's possible, given the correct uPVC profile
& associated window /door manufacturing equipment.

Practically I'd be surprised if anyone would take it on. Plus it
would most likely mean the door having to be removed & taken away
to do it "properly".

Can you find a catflap to suit the width anyway?

You might be able to fit one neatly in the lowest part of the
panel, then fit a shorter DG unit above it. The trickiest part
would, I think, be either transferring the weight of the DG unit
down to the bottom where the original DG unit now sits, or making
alternative arrangements...

If there is enough meat on the catflap bezels, you might be able
to hide a bit of ally? angle behind them, rivetted? to the sides
of the glazing rebate, & sit a suitably sized new DG unit in
that?

My limited practical experience suggests not all cats would cope with
such a difference in height between the flap and the step below. Do you
have a cat-flap sized bit of external wall where sod hasn't run gas
pipe, water pipe, incoming power, etc?

I'd say the easy way would be to replace that glass panel with something
equally as strong - say plywood of the same thickness as the glass.
Perhaps Formica covered to give a nice smooth surface.

Easiest no doubt. I'm not sure my daughter would find it
aesthetically pleasing though. It would also reduce the glass
area considerably.

Ideally I'd just like to know if it's possible to "glue" in a UPVC
crosspiece to reduce the size of the middle glazed part (and to
allow refitting of glazing bars etc.

No, unfortunately you will have to tell her it's impossible and the
cat will have to become an 'indoor cat'.

Either that she can take it out for walks on a lead, that way she can
ensure she's being responsible for her 'companion animal, that it
isn't cause car accidents as it runs in front of innocent motorists,
doesn't foul in other peoples gardens or kill their fish or wildlife.

Yeah, I do, except for the one that tears up one of the trees, wanders down
one of the branches that overhangs the flat metal deck roof and then jumps
from that onto the roof. Fortunately the tree it zooms up is visible from
where I sit most of the time and so I know when its going to jump.

I dont care about the expense, just welcome the neighbours
cats enjoying my jungle which is vastly better for a cat than

p.s. Our daughter is also a part time animal warden and much of the
time she's collecting dogs that have got out and been held by a member
of the public or taken to the vets etc. If the animal isn't chipped
and the owner comes forward they are charged to have the dog chipped
and also charged for the collection (and fined if they are repeat
offenders). If the dog has done any damage along the way the owners
can also be reported to the Police and subsequently charged and
further action taken.

Cats and other wild animals she often has to collect with a shovel.

It would, but being caged, fed and watered is still 'better' than
being mauled to death by a cat over several hours?

FWIW, I don't support the keeping of things like birds in small cages
(especially indoors) either. Owning a bird of prey (working a lure or
deterring feral pigeons) or racing pigeon would at least mean they
could be allowed to do what they naturally do for some proportion of
their lives.

We don't currently have a dog (we did have 3 at one point, all rescue
animals) because I don't feel we could give one what it would need.

We could have a cat ... and just let it out to roam the neighbourhood
all day but what would be the point of that? It's not that we live on
a farm and need any rodents kept under control and would rather
protect rather than kill any other wildlife we have out there, whilst
we still have it. ;-(

'Man's best friend is a dog' and not much else compares.

They make such good companion animals because they have lived with and
worked for us for millions of years and so now rely on us (and us
them) for lots of practical things.

I guess when they can train a cat to sniff out drugs or do mountain
rescue, I'd consider one as a companion animal (or when I'm old and
infirm, maybe I'd succumb (but I doubt it)). ;-)

Is it possible in this door?

I'm wondering about a reduced length window in the centre section
and if possible, a new crosspiece to enable secure glazing and
place to put a cat flap. Is this possible post-manufacture?

Does look difficult.

Or if you're lucky maybe there's a wall you can put a cat flap in using an extension corridor for thick walls.
