How to make your garden Hedgehog Friendly

Here is a great video made by the British Hedgehog Preservation Society on how to make your garden Hedgehog friendly.

Let areas of garden grow wild to mimic the hedgehogs’ natural habitat.
Have a log pile or two of rotting wood which Will attract: insects and other critters that hedgehogs will feed on.
Provide some form of shelter in the colder months by installing a hedgehog house, or through logs piles and compost heaps.
Don't be too tidy about picking up those fallen leaves as they will form a great home for beetles and other invertabrates that the Hedgehogs will feed on. Also the dried leaves will make good bedding that Hedghogs will pull into their sleeping accomodation.
Don't use garden chemicals such as slug pellets.
Leave out water and foods such as meat based cat food or a dried Hedgehog food.
Consider installing Hedgehog Highways by putting holes in garden fences/gates or planting hedgerows to help hedgehogs move between gardens.
If you have a pond put in a sloping edge or some hedgehog ladders so that they can get out if they fall in (see ours that we made).
Check out any long grass for Hedgehogs before strimming.
