GarLyn Zoological Park presently has 2 wolves housed in a large natural enclosure. Within the first couple of weeks of being placed in the large enclosure they started digging in the old dens and in the sand we have here in Michigan's Upper Peninsula it wasn't long before they had a den 15 to 20 feet long and about 2 feet in diameter and just the way they wanted it. They seem to be content with it now. We try to feed our wolves as much natural meat as possible by getting some road killed whitetail deer and snowshoe hare. We also get meat scraps from the local shops along with high protein, meat based dog food.
