Former there was a mixed exhibit with North American Porcupine and Striped Skunk here at Braunschweig. Zootierliste lists all three species together (the abovementioned two with Opossum), so what is the current situation?
On my first visit there were striped skuns in the enclosure instead of opossums. However, there are also striped skunks in two other enclosures in the zoo, which is probably why they were simply relocated. And I think there was a sign for Marmots as well. But currently the enclosure on the left is for Spotted Skunks (which I haven't seen in person) and the right is for the opossums (you can see the seperation as the ground changes from grass to earth). And the American Porcupines can either move over the two seperated enclosures or they are kept in two "groups".
@RonBurrgundy thanks a lot! Just realized that is an other species of skunk, Eastern Spotted Skunk is together with the North American Porcupine. The Striped Skunks live in two other cohabitation with Raccoons and with White-nosed Coatis.
