It would not be a one-time visit when a stray Russian cat wandered into the lynx enclosure at the St. Petersburg Zoo in 2008.
Six years later, the two remain inseparable and the feline couple, some say, have become like parent and offspring.
According to local lore, the calico was homeless and found food in the Lynx compound of the Leningrad zoo.
The video below was recorded in 2014 by a zoo visitor from behind glass.
