Just wanted to share something that seems to be working for me - I've created a new thread rather than adding to @Fat Controller's Fox thread because it was created to deal with a cat problem rather than foxes. (Actually I think it might well work for foxes, too, but I haven't had a problem with those since my old greyhound - predecessor to the one in my signature - chased one out of the garden, biting it on the bottom as it leapt the fence. I guess the word got round!) Anyway - there is a corner behind the shed where my garden adjoins three others. The trellis runs out and although the fence is still six feet tall, it was a regular route in and down for neighbours' cats, especially with a compost dalek below. I really don't want Ken chasing those, so first I tried adding a bit of clematis netting to the top of the fence, so that it wobbled around a bit if touched. That did help but we still had some regulars coming in. So I have now rigged up a plastic line across the space, and hung it with windspinners made out of old aluminium drinks cans. These move easily, rustle and tinkle gently and look quite pretty I think with all their different designs. At first they kept getting tangled up, so then I fixed the ringpulls on the line and that keeps them apart. So far it has been working - no more cats. Fingers crossed! The windspinners were easy to make - you just need some aluminium drinks cans, a knife and a pair of scissors. Lots of instructions on the web, eg here: With mine as I was fixing them to a line rather than a stick I just cut them into shape and then stabbed a hole through the centre with a bradawl.
