Now that was good!!!

But lousy design, a solenoid value would have been a much better approach.

And could drive a much more widespread spray too, so you dont just 'protect' you car.

I thought cats were smarter.

Be interesting to see what a much wider spray could do to cat behaviour.

Corse you would have a problem with everything else
that moves like humans and his kid getting sprayed too.
