Yes, he and his twin brother were rejected by their mother, and the twin died. After that, the zoo decided to hand raise Knut. He had such a strong bond with his animal keeper, but while polar bear cubs stay with their mother for two years, the two them had to be seperated much earlier because Knut grew too big for his human. And then in 2008, Thomas Doerflein died before Knut was even two years old. He always seemed to be kind of lost after that. I don't know how he felt about Gianna, the female they brought from Munich, but I figure if he enjoyed her company, it must have been another bummer for him when she went back to Munich. The last months, he spent with his mother Tosca and two other females, and all of them tended to mob him.

So far, they don't know why he has passed, but I've got a feeling he died of a broken heart.

This afternoon, they showed these old Knut shows on tv, you could see how happy he was with his keeper. It was strange to see this and to know at the same time that both of them have left this world...
