Haven’t got a garden but within 100m of my flat (in a city, not far from the centre) I’ve seen a badger and what I believe to be a steppe polecat. Exciting stuff.
Back home my mum’s garden had bats, the odd grass snake, weasels, hedgehogs, toads, foxes, mice, squirrels for days, all sorts as it backed onto a park. Even had a baby deer come up to the fence one day and stick its head through the gap 
Wish I had a garden.
