Campus police at Guelph University say they're searching for a snake believed to be loose in a building that houses the school's administration offices, cafeteria and food court.
They say the small ball python was reported missing Thursday.
Campus police and pest control specialists are searching the building for the four-year-old brown and black snake that is about 60 centimetres long.
Ball pythons may bite, so people are being warned not to pick it up.
But Hugues Beaufrere, chief of the Avian and Exotic Medicine Service at the Ontario Veterinary College, says the python isn't dangerous or venomous.
