Felidae Conservation Fund Felidae Conservation Fund (FCF) is a California-based non-profit organization dedicated to preserving wild cats and their habitats. The organization supports and promotes international wild cat research and conservation by collaborating on field research projects, partnering with other environmental organizations, and developing community outreach and education programs. FCF was founded in 2006 by conservationist and entrepreneur Zara McDonald. As a competitive marathon runner, McDonald twice encountered mountain lions during solitary runs in the Marin Headlands in
Felidae Adult tigers actually display elongated rosettes that now appear as stripes. Adult lions seem to lack any distinctive markings altogether.

The rosette patterns found on snow leopards, jaguars, and leopards all have a common origin. Fossil occurrences indicate that the Felidae arrived in North America about 10 million years later than the Canidae, and about 20 million years later than the Ursidae and the Nimravidae. Traditionally, five subfamilies have been distinguished within the Felidae
