In Leningrad (St Petersburg) Zoo, the oldest zoo in Russia, an European Lynx had a frequent visitor who befriended the big wild cat and now they are practically living together. This visitor is a calico cat who has bonded with the Lynx ever since the day she entered the enclosure.
According to the local people, the calico was homeless and happened to find food in the lynx’s enclosure. The lynx did not reject her, rather she became her surrogate mother. It seems as if the calico needs the lynx as much as she needs the little cat. They spend every day together and never leave sight of each other.
