Sorry to hear no hogs back yet and about the poor one who died. I hate even the sound of strimmers, but it seems you can’t get away from them these days.
I know what you mean about the A24 trap – another worry. Such a shame that fate and general elections worked against the petition – there are probably loads of them around now and I wonder how many people really set them up so that they can’t catch hedgehogs.
All we can do is hope for the best. I really hope you get some hogs back soon. I would keep putting the cameras out, you never know, they might capture some images of one in the middle of the night uninjured.
