I remember Spotted Hyenas in what is now the Bush Dog enclosure, between the "Small Cats" range, Tiger enclosure and the Snow Leopards. I also remember talking to a member of staff who told me that the hyenas, (then quite elderly), had escaped when vandals cut their wire mesh fencing during the night. Keepers/ security staff managed to return one of the pair to the enclosure but the other, heading downhill towards the perimeter fence, had to be shot to prevent it escaping the site into Dudley town centre. I don't remember when this was, but sometime in the nineties.
