We have! Hedgehog highway is going in the fence panel nearer the house after we had a very confused hodgepig doing laps... there are gaps under our side gate and around the garage but I must admit my first thought when I installed the fence was terrier containment.
Good stuff. It’s always worth trying to coordinate with neighbours as well if possible. If the whole road can do that kind of thing it’s even better. Depends on where you are I guess, but gotta help the little hedgehogs out!
Nice gravel boards you have there, have you thought about making some holes for hedgehogs?
