They used to be unheard-of in the UK but they're getting much more common now - especially in the smaller places. Off the top of my head, Edinburgh, Exmoor and the Palms at Stapeley all have them - and I'm sure I'm missing some obvious ones. London had them for a while but no longer, I believe. They're also about on the continent - Arnhem and Gelsenkirchen spring to mind.
Always Striped Skunks in Europe, though; I've only once seen anything different - a pair of Molina's Hog-nosed Skunks at Barcelona in 2002.
paradise wildlife park and tropical wings also have skunks.... i have worked with skunks for many years and i would never risk putting rabbits in with them and wouldnt put it past a skunk to catch and kill a peacock either.
Zoo Boise and Utah's Hogle Zoo both keep western spotted skunks Spilogale putorius. Although, skunks aren't all that common a display animal in the US either.
