Hedgehogs born late due to warm weather have been spotted "drunkenly" walking around as they are unable to hibernate.
The advice is to keep the hedgehogs warm and feed them
Charities have been inundated with the babies from second litters which have not put on enough winter weight.
"People are ringing up saying they've found a hedgehog that looks drunk," said Hugh Warwick of the Hedgehog Preservation Society.
"Hedgehogs are suffering from the early stages of hypothermia, they're beginning to shake and to wobble."
"If you find one keep it warm, feed it some cat food and put it into a cardboard box until it puts on some weight, then it can be released back into the wild to hibernate," advised Mr Warwick.
