The wolf pups, that almost seem as big as their parents, are now on display, as are the young Dholes. “Earlier they had two babies, Prema and Nanda,” Dr Hiremath said. If the attempt to mate the two rhinos becomes successful, Saraswati may give birth to her fourth calf after a gestation period of 15 to 16 months. In this period, she will be by herself as male and female rhinos go their separate ways once they mate. “We have had quite a successful run in breeding various animals over the past couple of years and we hope we can succeed with the rhinos too,” Dr Hiremath said.
