Have you found a hedgehog out in the daytime? 

As hedgehogs are nocturnal, being out in daylight means he/she is in trouble.  And will definitely require your help.

Nowadays, eviction from their habitat is all too common, but more likely your casualty is orphaned, injured, poisoned, ill, cold or starving and needs help.  If he/she does not bother to curl into a ball he is not tame but ill.

If he/she is laid on his side then the condition is serious.  In winter he/she must weigh 1¼lb or 500g.  he/she may be too small to survive hibernation.

The following are signs that your hedgehog urgently needs expert help or a vet:

• green faeces, diarrhoea or blood
• broken limbs or wounds
• skin crustations or baldness
• if his skin hangs loosely enough to reveal his bone structure
• if he coughs or wheezes
• has obvious dental problems
• feels cold to the touch
