Surat, May 08 (ANI): Royal Bengal Tigress named Shambhavi, which gave birth to four healthy cubs last week at the Sarthana Nature Park in Surat, has been separated from the cubs since the tigress is unable to take proper care of the cubs. Out of the four cubs, one succumbed to death due to weight loss and improper feeding. Other three cubs are being kept under observation. Necessary treatment is being given to save the cubs from infection.
