If you find an ill or injured hedgehog it will probably be suffering from hypothermia, even in summer
Never try and force feed a hedgehog. The danger is the fluid/food will be inhaled
Place it on a hot (but not boiling hot) water bottle wrapped in a towel and put in a cardboard box or recycle box lined with newspaper, cover the box in a blanket, place in a quiet place to warm up and phone us immediately
Hedgehogs that need help are:
Orphaned hoglets - found out of the nest in day, the nest has been destroyed or the mother killed/injured
Injured hedgehogs - with open wounds, fractures, bites, burns, or trapped in some way.
Sick hedgehogs - usually found out in the day, thin, dehydrated, possibly poisoned, or with breathing problems. Hedgehogs that are unsteady on their feet (wobbling, rocking) or with flies around them.
Autumn juveniles - young hedgehogs born late in the year, weighing under 600g from September onwards - especially if out in the day.
Hedgehogs that should be left alone
Healthy hedgehogs will often rouse from hibernation for short periods even in cold winter weather. Do not assume these hedgehogs need help unless they are underweight or obviously unwell.
Adult females in summer that are uninjured but found out in daylight may be nursing mothers. Any large uninjured hedgehogs found at night (e.g. in winter or in the road) and picked up should be put back away from the road but near where found.
