Hello Gary,
When we moved into our present house some 10 years ago we found that our neighbour had 19 cats that she fed. Most of which were ferral cats and lived in the wood at the top of our garden. She would come out and shout "kit e kat" and you could see them come from all directions. The problem was that their garden was like a jungle so all of the cats seemed to use our flower borders and lawn as a toilet.
We bought one of those sonic repellant things, £35, Extention cable £7, mains transformer £25 and what happened?
Instructions said to place it where the cats normally come into your garden.
O.K this was the wall between us and next door where they used to jump over.
Set it up and waited. First cat over landed right by it and jumped two foot in the air and shot off back over.
Great result I thought until a couple of minutes later he reappeared with another scraggy old cat who stood on top of the wall for a few seconds, jumped down by the sonic scarer backed off a little, then approached very warily turned his backside to it and peeded all over it.
It was a complete failure. No matter where I put it, if they passed it they would jump but then come back have a sniff and pee over it
I was able to solve my problem with these PIR operated water jets as I have a large garden. I have two permanently coupled up and keep moving them around so my garden is cat free.
I have just been into the workshop and found this sonic scarer, the plastic lens on the front is missing but it appears to be in working order. If you would like to try it out it is yours for the cost of the postage.
Cheers Alan.
PS it no longer smells of cat pee
