Mister Tiggy-Winkle, an African Pygmy Hedgehog from Summerfield Farm and Zoo in Belvidere, Ill., stretches his paws in the air as children watch on Oct. 6, 2012, at the Autumn Harvest festival's petting zoo booth in Arlington Heights, Ill. The petting zoo had goats, sheep and a South American oppossum among others at its booth. A zoo employee told festival attendees facts about the animals and let children pet them.
It was a very cold day, and the petting zoo employees did a fantastic job of keeping the animals warm. The hedgehogs and short-tailed opossum were kept on a heating pad inside a covered cage.
