30-degree frost made chimpanzee Bonya from Chelyabinsk Zoo to wear soldier greatcoat. The animal has even learnt how to salute. Heat-loving monkeys are kept warm in written off ammunition presented by command of military automobile school. But only warm clothes couldn`t improve the situation. Zoo was provided with powerful heating fan. 2 fans heat rooms, where Bonya and othe chimpanzees live. One is placed in poultry-yard with 2 dozens of heat-loving birds. The only animals, which don`t mind sever frost, are artic bears and Ussuriisk tigers. They walk in open-air cages and examine closely Zoo workers, who muffle up in fir-coats and valenki.
