I have a wooden hedgehog house which I have had for about a year now.
I knew they were around as I had seen droppings & put out some hog food. When I first got the house I put straw outside & a little inside. It took a few nights but the straw was taken in and taking a peek by lifting the lid it had made a wonderful round nest. I couldn’t tell if there was a hog in there though and still don’t know, although they are around every night eating the food & drinking the water I put out. We see them occasionally around the food if we are up after 11pm – they are so cute. But we have never seen them around their house which is at the back of our garden.
I love to think I am helping the hedgehog community. 🙂
