We’ve been very fortunate to have hedgehogs visiting us regularly over the years. We bought an infra red camera to use at night about 3 years ago, and each year it has recorded our prickly friends visiting, so I’m assuming they were visiting prior to us having a camera, too. Our garden and those around us are easily accessible for them. We don’t put out food, just water, although a neighbour leaves a small dish of dog food overnight and it’s always gone the next morning (I realise it might not be the hedgehogs alone enjoying that, though, which makes me a bit wary of doing the same).
