Hi bramleyb
Well done spreading the word about hog holes! Brilliant news.
Also good news that you have 4 hedgehogs visiting. If you are able, I would try to discourage the hogs and the fox eating side by side. Maybe put the wet food further away. Hopefully things go well, but remember that foxes are predators and some (although seemingly not all) do turn on hedgehogs. The hedgehogs are more vulnerable when they’re eating and may not be able to roll up soon enough if the fox is closeby and they are lulled into a false sense of security.
That’s really useful your neighbours feeding the hedgehogs, too. Less worry if you ever go away for a while!
I hope all goes well with the hedgehogs. Happy hog watching!
