That’s a good idea and good that the hog house will stay. If you could leave a message asking the new tenants if they could make sure there was at least water always available, that would help, even if they didn’t want to feed. You never know, they might be excited that there are hedgehogs around! Did you have any luck with the other neighbours? Maybe they, too could leave out water, if not willing to feed. It doesn’t seem so important with all this wet weather at the moment, but when we have dry spells can be a life saver for hogs.
If you go to the BHPS site (click on their logo above), there are lots of posters/leaflets about hogs. Maybe you could leave a copy of for instance https://www.britishhedgehogs.org.uk/leaflets/A-guide-to-helping-hedgehogs.pdf
somewhere that the new tenants would find it.
Or if you leave a list of useful numbers, maybe you could add something to that and include, i.e. link to Hedgehog Street, local hog carer, hog food supplier, etc.
Good luck.
