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

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


(Obviously not using PIRs is an option but the idea of wires etc to
window / door sensors really isn't practical. A few PIRs will 'cover'
the required rooms and I think there are routes for wiring, if we can't
find a wireless solution.)


A few months ago I asked about using PIRs with purrs (sorry, I couldn't
resist) and was told that the "pet proof" ones were not very effective.

We had one fitted in our garage in an attempt to reduce false triggering
due to bats.

It didn't work.

But then, the bats aren't pets.

And they can fly....
