So sorry hear about the hogs, Dizzydog. The way I see it, we’re here to share the sad times as well as the good ones, so don’t worry about that. As you say, it is incredibly sad that that a hog can be killed on the road, just like that. Whether they are our visitors or not, they are hedgehogs and we all go to a lot of trouble to try to help them. Each and every hedgehog is precious. I do feel for you – it is always much harder when it is close to home.
Perhaps it is a good time to redouble our efforts to try to get more holes in fences, hedgehog friendly gardens, etc. so that hedgehogs don’t have such a need to cross roads to find suitable habitat. Hedgehog Awareness Week coming up 6th – 12th May would be a good opportunity to try push the message. I came across a good poster on the BHPS site: https://www.britishhedgehogs.org.uk/posters/Find_The_Gap.pdf
There are quite a few posters about various hog related things which you can download.
Probably the last thing on your mind, but it’s worth reporting the 2 poor hogs on the Big Hedgehog Map. It all helps to show the reality of what is happening with the hogs.
