Hi Francesca
Well done with all the efforts you’ve been making – very dedicated! Especially if you are still not seeing hogs yourself yet. Sorry to hear you haven’t had much in the way of replies, but as you say, hopefully there are some more hog holes in fences. But some people could have been away on holidays, busy with children on their Summer holidays from school, etc.
You really do deserve to see some hogs yourself. Making your garden as wildlife friendly as possible can help. Some tips in here https://www.hedgehogstreet.org/help-hedgehogs/helpful-garden-features/
Leaving water available is always a good idea too, even when not offering food as well. Even when hogs can find wild food, they can’t always find water naturally.
Good luck and keep up the good work!
