It has been my observation that tame ferrets are very good at hunting tame rodents. Someone bought a large number of mice from a store which then got lose in the empty store room. My room did have wild mice in it, which I would see from time to time. The ferrets never saw them or reacted to them slightest. But when I took them to the invested store room, they immediately lept to hunting. Got every single one of the buggers in no time flat. They weren't interested in eating them mind you, not that I was going to let them anyway. My theory was survival instincts. Wild mice instinctively masked their scents or keep things like fear under control. Caged mice were scared whittless and could attract a blind, deaf ferret with a head cold.
