Having just opened their eyes a few days earlier, orphaned Pacific fisher kits live inside an incubator at the Fresno Chaffee Zoo. Their mother appears to have died of predation, but rodenticides from pot grows are found in 100 percent of all dead fishers, and can be a contributing factor in many deaths attributed to other causes. Mothers might also transfer toxins to their young through their milk, according to biologist Craig Thompson with the U.S. Forest Service.
Biologists are taking advantage of this rare rescue to give the kits a second chance in the wild. They were reintroduced into Yosemite National Park in September 2015.
