We had a sensor light fitted in garden some time ago to see when our fox came to the garden. One evening when the light came on we couldn't see anything straight away and then we saw two hedgehogs munching on bird food in the sanctuary. I had to go out to check if there was a hole in the cage but there wasn't the hedgehogs seemed to elongate themselves and go in and out with ease. They have been back many times but don't always go into the sanctuary, but have bought hedgehog biscuits for them. So lovely to see them we have had a couple of really small hedgehogs they are so cute.
