I was discussing fitting a burglar alarm with my son-in-law and the
problem of their cat occurred to me.

While they could confine the cat to a room not covered by a PIR, the
layout of their house would make this far from ideal in a number of ways.


I can't believe I'm the first person to think about this problem- what
to the millions of people with cats/dogs do?


Pet proof sensors. Basically, the lens is designed to ignore low moving
objects like cats or dogs. Work OK here.


I'm not a cat owner but don't they climb on sofas etc?


sofas, stairs, ceiling fans, aerial walkways, you name it. Depending on the nature of the cat in question. There are even ones that will climb up things to get near the ceiling and leap out when people enter.

Daughter's one seems to sleep a lot.


16 hours a day is the norm. Much more can be an indicator of pain.

They are also trying to work out
how to fit a cat flap - the only available door has glass panels.


A glazier can probably sort that for you.

There
is a wall into a conservatory but I'm not sure if you can fit a cat flap
in a wall.


certainly can.

They tell me you can get flaps which are coded to the
microchips that each cat has.


yes, I looked into those and was unimpressed. So are most cats.


We found that our cats didn't like the noise of the motor releasing the
latch, but that they got used to it.
