I was discussing fitting a burglar alarm with my son-in-law and the

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?

Daughter's one seems to sleep a lot. They are also trying to work out
how to fit a cat flap - the only available door has glass panels. There
is a wall into a conservatory but I'm not sure if you can fit a cat flap
in a wall. They tell me you can get flaps which are coded to the
microchips that each cat has.
