City may improve zoo\'s bison pen

Officials in Elgin, Ill., have taken steps to improve the fencing for the city zoo\'s bison pen and may add more bison to the exhibit. The Elgin City Council gave preliminary approval Wednesday to soliciting bids to improve the fencing at Lords Park Zoo, but no funding for the project has yet been approved, the Chicago Tribune reported Friday. The improvement project is being spearheaded by Friends of Lords Park Zoo, which has been pushing for officials to improve the facility. The zoo\'s exhibits include bison, deer, elk and farm animals. The zoo has only one remaining bison, Pokey, after the animal\'s companion, Cahoya, died recently at the age of 24. Officials said they have been considering offers of bison donations.
