Luxuries help zoo animals stay hot in winter

Underfloor heating, an incubator and an indoor pool are among the luxury amenities that have ensured that animals at a zoo in Jiangsu province have remained warm and comfortable over the winter.

Keepers at Nanjing Hongshan Forest Zoo even give some of the animals food that has been prepared in a microwave oven.

An incubator designed for premature babies has been installed for the zoo's mongooses.
