i seriously doubt that wild LMB get mammalian prey items more than a couple times a year in the wild, in our tanks their diets tend to be limited to just a couple food items at best so there is no good reason to feed mice frequently(more than a couple times a year) in our tanks. yes there are mouse shaped lures, so what, i could make a lure shaped like pres. bush and catch bass on it, and although i know we wish we could feed him to a bass, it wouldn't mean anything, bass will hit just about anything. just like bullfrogs will eat everything, including mice and other frogs but a diet of frogs would be very unhealthy. btw, i have seen multiple videos of bass eating rodents in the wild, off the top of my head i can recall one of some guys throwing a squirrel in and another of a chipmunk being thrown in.
