I need to install a cat flap in my kitchen wall. It is a single skin brick
wall (1930s red brick) with plasterboard and insulation behind.
How easy is it to cut the hole out for this? I have some long masony drills
etc, but am unsure as to how much you knock out. i.e. can you drill holes
in a line through the brick to create the hole of the required size or do
you have to knock out the surrounding bricks and fill in around it
Apols for sounding like a novice, but have never had to do this before.
apply template, drill a series of holes to suit, knock out the hole
with a 2" bolster chisel or SDS chisel, fit catflap inner, infil voids
with either mortar (hassle) or builders foam, fit catflap.
make sure you've bought a magnetic catflap or every cat in the
'hood will be wazzing up your sofa and stealing tiddles food.
Won't make any difference if every other cat also has a magnetic collar.
However, cats are very territorial, so if the neighbourhood moggies come
in either Tiddles or his owner are being a bit of a wuss.
I made one very many years ago, before you could buy them.
Trouble was, cat would arrive back home with a selection
of nuts, bolts, and other ironwork stuck to it. I gave up
That happened to my cat at the end of its life. Someone else's
cat found it rather unwell, and took it home. The owners, not
knowing whose it was but realising it was ill, took it to the
vet. We found it a day later through a pet tracing charity, but
sadly it died a few days after that, aged nearly 22.

The ?electronic? Staywell ones with different coloured keys are IMO better.

Yeah, and unless you use one that has a big enough inner liner- or more
likely you can get extension 'rings' for it. to line the hole.
I used an earthenware square liner from builder merchants (used for
lining for airbricks I guess?) I fixed the catflap to a slightly larger
square of 9 or 12 mm ply and then fixed that to the wall. Much easier
than trying to fix the catflap to the brick directly near the edge of
I had meant to take off the ply (WBP) and varnish it. But never did, it
was still perfectly fine 7 years later when we moved.
I've done this in my kitchen as I didn't want to hack holes in the
kitchen door. This goes through a double skin wall. This lets them out
into the utility area then there is another cat flap in the outer door,
having taken out one pane of glass.
The cat flap in the kitchen is quite a simple one and the more
elaborate one to keep the stray moggies out is the outer cat flap.
I would recommend Pet Mate as a brand, when it comes to cat flaps. They
are brilliant at customer service, sending replacement parts sometimes
FOC, or really very cheaply.
(this doesn't imply that the flaps are badly made, but that we had a
large (18lb) energetic cat who went through a locked flap at high speed
when spooked by a big dog; he also broke the occasional latch, or lost
his magnetic key).

Stitch drill the opening as you first mentioned the knock out with
hammer and bolster ( if you dont have a hammer drill with rotary sto
which allows you to chisel it out easily).
The cat flap surround should cover the raggedy edges of the hole in th
brickwork, but make it as neat as possible and try and drill the hole
close together, otherwise you may find you self making good th
brickwork that was supposed to stay intact
FWIIW I've put fixed several Staywell flaps designed for doors onto
brickwalls. Each time I hacked out the birckwork approximately true
(drill through with a masonry drill -preferably SDS- then use a bolster
to join up the holes: messy but quicker ways need more sophistacated
SDS drills & other tools). Then I instal a timber liner ex 22mm
(actual) PSE timber and screw the staywell flap to that. Fixing a flap
on oboth sides of the opening gives makes it almost draught proof.
Your wall is liable to be soft brick and knackered lime mortar, and if
4" not scoring much on stability either. So go gently with the
chiselling. Wont be a prob as soft bricks are very soft.
Re larger walls with dual catflaps, creating a tunnel, this works fine
with some cats, but a lot will simply refuse to enter a small closed
it will if it knows it's dinner is on the other side and it'll soon get
hungry enough to overcome it's fears, if not you have no more
cat infestation. job's a good un.
hahahhaha, cats survive for weeks trapped down holes. it's a wild
animal, treat it like one and it will reward you, treat it like a baby or
a small child and it will crap in your house, moult hair all over /your/
bed, pee in your house etc, etc.
/plus/ how can a 18" long cat get stuck in a 9" tunnel LOL
ergo dead cat or it buggers off to another sap who'll take it in.
and I know why YOU might me predisposed to say that, do you ?
A parasitic microbe commonly found in cats might have helped shape
entire human cultures by manipulating the personalities of infected
individuals, according to a new study.
Infection by a Toxoplasma gondii could make some individuals more
prone to some forms of neuroticism and could lead to differences
among cultures if enough people are infected, says Kevin Lafferty,
a U.S. Geological Survey scientist at the University of California,
In a survey of different countries, Lafferty found that people living
in those with higher rates of T. gondii infection scored higher on
average for neuroticism, defined as an emotional or mental
disorder characterized by high levels of anxiety, insecurity
etc, etc. clue yourself in, all you BRANE are belong to CAT LOL
