Not much, too urban. The cats seem to find plenty of bugs to stalk though and there are the usual slugs, snails and spiders - shook my garden shoes (battered ones for mowing etc...) out the other week and ended up screeching and a spider leapt out of one at me! Next door's dog usually comes and snuffles his nose under the fence at me if I'm sat on the back doorstep.
My parents get more back in Shropshire. In the past there have been badgers (think they've moved due to building works), hedghogs, a heron after the fish in the pond and even a peacock (noisy beggar!) - a guy who lived nearby has some and they go wandering sometimes. The badgers were gorgeous, my parents have quite a long garden up a few levels and they used to leave stuff outside a shed right at the top so they've trigger the security light on the shed without feeling threatened close to the house so we could watch them.
