Zelenogorsk, a mature Pallas’s cat, has been a resident of the Novosibirsk Zoo since 2014. At approximately 10 years old, his precise age remains a mystery, as he was brought to the zoo directly from the wild. As a prolific sire, Zelenogorsk has fathered numerous offspring. His progeny can be found in various zoos worldwide, contributing to the preservation and understanding of this unique species.
