Having bought a 32litre underbed storage box (ours was £4), we took a white board pen and marked a doorway for Hedgie.
Drilling small pilot holes at each corner, a sharp craft knife was
carefully used to cut the plastic - it was brittle so there were some sharp splits. After removing the "door", the rough edges were then filed and covered with electrical tape.
drill to make a small slot, then threading a cable tie through (it is rather fiddly but J persisted). Making sure the lid would still open, using the cable ties to form a hinge, the ties were tightened (don't overdo it - you need to get in to replenish supplies)
Placing the food bowls at the opposite end of the box to the doorway, we set the wildlife cam up and waited to see who visited. Night number one was only tabby cat neighbour but he didn't access the box and we're hopeful Hedgie will soon be eating happily.
UPDATE
Second night's activity on youtube - an early visit!
