By eight in the evening it decided it was time to go walkabout. As I was watching the monitor I saw it leave and dashed through to the kitchen to see where it went. Not a thing in sight. It had taken a route hidden from my view. At my bedtime I saw the Hedgehog at the food dish. After a while it wandered back to the hog house but came out again almost immediately. Looking through last nights captures it revisited the food dish several times but must have found somewhere else to sleep as this morning the house is deserted.
It is disappointing but at least I now know the house will be used. For those readers who may not have seen the photos of the hedgehog house when I first got it here it is.
I ordered it untreated and the first thing to do was to treat the outside of the house. Next the black and white board camera was installed (seen in the bottom two right hand views) along with some bedding - old leaves and hay.
