When I was a teenager a friend of mine did animal rescue and I remember helping to feed baby hedgehogs (so tiny they had fluff, not spines) with a tiny bottle and teat.
10 years ago, where I live, in an inner city street, I was making friends with local feral cats (now my cats) who visited through the cellar window (their 'drop-in centre') but there was a plate of cat biscuits on the pavement and one night, hearing it rattling, I peered out the window and came face to face with ...a hedgehog!
