Morning! I have just had one of those special offer emails through from Amazon telling me there is an offer on the Contech water scarecrow £38.99 with free delivery. This is an excellent product (imo) and well worth the money instead of spending out on various other recommended deterrents. This works and doesn't go out of date, disappear with the rain etc. it is moveable and just needs an outside tap. I think it's good timing for the beginning of the season to stop cats doing what they do in newly turned soil or on emerging seedlings etc.
I have no connection with the company, just own one and can recommend it.
