The idea that is a good idea to feed in a seperate enclosure is right up there with "balls require constant humidity in the 60% range" (among others). The fact is, this practice is just something someone somewhere thought was probably a good idea (and then passed on down the line). It is simply not borne out of any real science. Snake feeding is triggered by visual, odor and thermal cues (some data suggests CO2, vibration may also be cues in some species)...location is no issue whatsoever.
To the poster who advocates feeding in a seperate enclosure, that's fine...do what works for you. The fact is though, it certainly not necessary, and for many fussy feeding BPs, probably a bad idea. New environment = more stress = less likely to feed.
Finally, if you follow the logic....feeding in the enclosure = a feeding resonse every time the cage is opened. Well then, if you move the snake to feed, wouldn't it follow that you would get a feeding response every time you move it? (pausing as lightbulbs go off everywhere)
By guys....just hit my "feed in another enclosure" threshhold.
