Sanjay Gandhi National Park’s sole white tigress, Rebecca, who has been undergoing treatment for cancer recently suffered a relapse. The tigress has been unwell since last week and had even stopped eating for a few days, causing great concern to the park authorities, who are now keeping a close watch on her.

18-year-old Rebecca is the national park’s only white tigress. She was diagnosed with melanoma, a type of skin cancer, in her eye. File pic
