A brown bear tried to break a tempered glass wall of its cage at a zoo in eastern China, causing cracks in the glass, mainland media reports.
The adult bear was said to have had a “sudden character change” and become agitated on Wednesday night and had to be forced to return to its cage after the zoo in Changzhou, Jiangsu, closed, the China News Service reported.
The bear keeper was quoted as saying it could have been because the bear had eaten too much food tossed into the enclosure by visitors, including puffed and fried food that could affect the animal’s digestion and make it uncomfortable.
The bear kept smashing its body and paws against the glass wall of the cage around 8pm on Wednesday, causing cracks to appear.
Zoo employees anaesthetized the bear to prevent it hurting itself at 1030pm, and repaired the broken glass wall, the report writes.
The bear has been isolated from other animals and is receiving therapy as anaesthesia could impair its health significantly and it will take 3 to 5 days for it to recover, the report said.
More than 10,000 visitors flocked to the zoo in Yancheng every day during the week-long National Day holiday, and some tossed food to the animals, the manager of the animals’ department of the zoo was quoted as saying.
