Our neighbours cats are frequently in my garden. Last summer they kept shitting at the bottom of our slide and killing birds a our bird feeder. We installed plastic fence spikes to deter them and the neighbour knocked on our door complaining his cats might get injured and that cats have the right to roam.
We have left the spikes up which has stopped them running across the fences to catch birds but the cats continue to come in through trees at the back of the garden and now have adopted our new garden sofas. We bought some of those ultrasonic sounders things but they are not making a difference. We spent £90 on sofa covers to prevent the cats sleeping on the garden furniture but every morning when we go out the cats shoot from under the covers - this morning there’s wet cat hair all over the cushions. I bring the throw cushions indoors but not the seat as back cushions as they are huge and there’s loads of them.
I feel pissed off that I’m going to a lot of hassle and expense of buying things and covering things for someone else’s pets to use.
