It's a tragic fact of life. Celebrity polar bear cub Knut, now almost five months old, is gradually mutating from a fluffy porridge-lapping cub into a heavy bruiser with a penchant for meat off the bone. But the visitors are still flocking to see him.
Knut's days of extreme cuteness are numbered now that he has acquired a markedly longer snout and weighs a chubby 17 kilograms (37 pounds), twice as much as when he first appeared before an adoring public five weeks ago.
Ah well, it happens to the best of us. It's such a short journey from being cute to being "a case".
