If you were by some reason taking care of a hedgehog, please remember, they have some kind of a homing instinct. They will try to come back to the place they lived. Some tips when releasing a hedgehog:

• Release him in the SAME place you picked him up
  
  
• Do the release during the night
  
  
• Check that there is the access to fresh water in that place
  
  
• Do not release them from November to March or from end September to May (northern Sweden)
  
  
• Avoid releasing during periods of draught
  
  
• It will be difficult to release a hedgehog which you became a friend with, stop touching him and being around so much, so he can adjust to being alone
