Spud is a hedgehog brought to St Tiggywinkles Wildlife Hospital (Aylesbury, Bucks) when he was found to have a dermatologic disorder. The condition appears not to have been precisely diagnosed, though it looks like an eczema or an exfoliative dermatitis.
Since spines are hair-equivalent dermal appendages, the disorder has left Spud without spines. Those unfamiliar with how hedgehogs should look can get a cute overload at Google Images.
