I remember occasionally finding hedgehogs in our garden in Leeds when I was a kid. We generally used to give them bread and milk, although they eat insects, snails, frogs, toads, snakes, birds eggs, carrion, fruits, mushrooms, grass roots.
I was with an Iranian friend when she saw one for the first time, and that’s when I realised how very odd they look if you’re not used to them.
They’re related to shrews, but only distantly related to porcupines.
And I found this rather sweet story from Russia, where an abandoned baby hedgehog was adopted by a mother cat.
