A STUDENT was jailed for 90 days yesterday for roasting a hedgehog in a microwave oven. Lee Burden, 18, from Birmingham, admitted a charge of cruelty with intent to cause unnecessary suffering at Henley Magistrates' Court, Oxfordshire. The case was one of the first to be brought under the Wild Mammals (Protection) Act 1996, which is designed to prevent deliberate cruelty to wild animals.
