Tosca, who rejected her cub Knut at birth in 2006, was nearly 30 years old, the zoo said.
Knut, who died aged 4 in 2011 from an epileptic fit, became the zoo’s star attraction after Tosca rejected him at birth. That would have normally meant death but the cub was saved against the odds and reared by zookeeper Thomas Doerflein.
“Deaf, blind, and disoriented, Tosca was found stumbling around in her cage on Monday,” the zoo said in a statement.
“She lost her sense of smell. It was a pathetic sight. Veterinarians, animal protection officials and zoo officials came to a decision to put the elderly bear out of her misery.”

Tosca was born in Canada but spent time in communist East Germany’s state circus has been at the Berlin Zoo since 1998.
At the height of the Knut frenzy in 2007, thousands of visitors from around the world flocked to the zoo to see the rescued cub frolic in his enclosure.
Knut’s survival inspired a dizzying array of merchandise. Other German zoos have tried to repeat Knut’s fame by promoting other celebrity animals but none has ever come close.
