Hedgehogs go Hog Wild!

Recently, Mrs.Nev noticed a patch of earth, scratched up by our back door... "It's the Hedgehogs!" she said. "They're going mad!" This makes perfect sense...our kids don't go scritch, scritch, scratch on the ground, like that...& anyway, it only happens at night! It reminds me of the "Old Jumping Hedgehog of Ranui," - we used to go to a social club in Ranui, in Auckland; there was a Hedgehog there, that came out in the daytime - and danced around, doing spins! Don't know if these Hedgehogs spin, but they certainly do scratch!! :D) They've srcatched-up an area of about 4 sq. metres...
