| I don't know if the ultrasonic thing works, but as the battery runs down you hear this irritating peeping sound continuously - I know, because whilst working in the greenhouse I was subjected to it for hours on end. Don't know about deterring cats - it could deter me!!!
Charity shopping again, I've bought one of those rubbery plastic snakes. If nosey cats approach and touch it, the snake moves and it is supposed to frighten the cat. |
