Berlin zoo ends Knut's appearances with keeper

The show is over: the Berlin zoo's fast-growing polar bear cub, Knut, won't be appearing anymore with the keeper who raised him. The zoo said Monday that it has ended seven-month-old Knut's twice-daily public appearances with keeper Thomas Doerflein. The playful pair have delighted audiences since Knut - then an irresistibly cute 9-kilogram cub - made his first public appearance in late March. Now nearing 50 kilograms, the boisterous bear, who will remain on public view, will have his enclosure all to himself.
