I live in an area which what seems like quite a high cat population, there's usually about 7-8 I see roaming round on a daily basis. I'm not sure if this is why NDN has put metal spikes on their fence, but they have put two lots of very sharp, metal spikes on their garden fence corner (including part of our shared fence) which seems like it is to deter cats going into their garden.
I get it's very annoying having animals coming into your garden to do their business but these spikes are ridiculous, if a cat jumps on them they're going to end up with an injury. There has also been absolutely no discussion as to whether I'm happy with them going on our shared fence, and it isn't the first time they've made changes to the fence before without consulting me.
I've looked up about fence spikes and from what I can see the spikes need to be plastic and blunt as to not cause injuries. AIBU to think this is harsh?
