Start dropping hints that you would like a crowscarer for your birthday or
Christmas. Cats come into your garden, get squirted with water and it
happens next time and next . . . . They do not hang around long enough to
leave their calling card, and very soon they do not even come!

I only switch mine on now and then and I think even the vixen which used to
call round has got the message. Mind you, when I first had it I forgot it
was on once or twice and had showers to remind me!!
