If you are worried about the health of a hedgehog, at any time, you can ring BHPS on 01584 890801 and get contact details of your nearest hedgehog carer/rehabilitator and discuss it with them. You can talk to them and give them better details and they can ask relevant questions which you will have the opportunity to answer.
