Lynx at Night
The Canada lynx—seen here on the shore of Loon Lake in Ontario, Canada, in 1906—is listed as "threatened" under the U.S. Endangered Species Act.
Though lions, tigers, and cheetahs often occupy the conservation spotlight, their smaller cousins deserve some attention too. For National Cat Day, we reached deep into our archives to pull up portraits of a sampling of the 30 small cat species.
