Volunteer Feline Detectives (Panthera leo) were a pack of detective lions that once lived in the caves of the Mortmain Mountains. The lions were once noble creatures trained by V.F.D. to detect smoke, and it is revealed in The Bad Beginning: Rare Edition that Beatrice and Bertrand Baudelaire once worked to train them. At some point, the fire-starting side of V.F.D. (including Count Olaf and his associates) took control of the felines. The whereabouts of the remaining Volunteer Feline Detectives is currently unknown.
