For those animals who live in the open, temporary shade of hay has been put up. “Wooden boxes have been put up for small cats to spend their nights in. The floor of all the night houses has been covered with a wooden plank to provide insulation from the cold. 200-watt bulbs have been installed in their enclosures and, in case of birds, straw bedding has been prepared and water is changed thrice every day,” said Dr. Samrendra Bahadur Singh, the veterinary doctor at the zoo.
Also, the diet of lions, tigers, and leopards has been increased by around 20% to provide them more energy. However, reptiles like crocodiles go in hibernation during the winter and their food intake almost stops, Singh said.
Special care is taken of frugivores like chimpanzees who are dependent on fruits. Such animals are more prone to cold and in order to boost their immunity, they are given ‘chyawanprash’ and boiled eggs during winter. Rhinoceroses are given additional minerals and elephants are given extra sugar cane to provide them with energy during this time of the year.
There are 1,100 animals of different kinds in the zoo and there are two veterinary doctors to monitor their behavior on daily basis.
