Hi thepodd
Don’t worry, I anticipate the hedgehog will be back – especially if he knows there is a good source of food! Many of them don’t like lights which suddenly go on, but don’t seem to mind if lights are already on when they arrive and stay on for a longer period of time. But, they vary a bit and some will become used to security on/off lights.
If there is one hedgehog around, there are likely to be others, so you might end up with more than one visiting – once the message gets round!
Good luck. Keep us posted.
Happy hog watching.
