From ANNE URSELL
One has to have some doubts about the Russian hedgehog story (Feedback,
9 December). I took part in a hedgehog survey for the Department of Zoology,
Royal Holloway College, London, which involved colour-coding visiting hedgehogs.
The friendly hedgehog coming to me every night for his evening meal turned
out to be 17 different hedgehogs.
