Put out some water to help the hedgehogs and other wildlife. My local rescue is inundated with hedgehogs at the moment. Mostly abandoned dehydrated babies. A lot don't make it 
Leave food too if you can. Any cheap dry cat food is good. If you have no food, don't worry, just leave water. Leave lots of dishes scattered about your front garden and back garden and remember to fill them before it gets dark.
Other things that can help:
Try and make sure fences have gaps so the hedgehogs can garden hop.
Be careful when gardening and leave plenty of cover for wildlife to escape under.
If at all possible don't use slug pellets and other chemicals around the garden.
But most importantly, get the WATER ready for tonight and help our prickly friends stay healthy and feed their babies ❤
