Claim summary · not a verbatim quotation
Fifty percent of the diet of mountain lions in the San Francisco Bay Area is domestic pets.
The finding
What the evidence shows
The 52 percent figure comes from California wildlife officials' study of stomach contents from 83 mountain lions killed under depredation permits, statewide, and it measures how many lions had pet remains rather than a share of the Bay Area diet. A Bay Area GPS study of four lions in Sonoma and Napa counties found that 75.7 percent of identified prey items were black-tailed deer. Falsifier: a Bay Area diet study showing that pets make up about half of prey items.
