Hi!
When it comes to the old "in or out" debate, I am of the external cohort, preferring to feed my sneaky ones in a tub which is separate from their housing. While there are many pros & cons, I actually began this habit because I used to cohab my adult corns. I learned the hard way that if one finishes eating before the other, that one can actually become a potential meal for another, as Lilly once grabbed onto a mouse halfway into Bozo's mouth and by the time I noticed, Bozo's entire head - mouse and all! - had to be extracted from Lilly's throat! :madeuce:
A close call to say the least!! (This was when they were all a year old and Lilly grew faster than the males for some reason, though they are about two feet longer than her at 8 years old).
Now that they are all living separately (thanx to the suggestions of those on this forum), I have maintained my habit of feeding them all, including my yearling, Ozzy, outside of their regular enclosures. It prevents any mess a mouse will leave behind, prevents a snake from swallowing substrate, ensures I SEE whether or not the meal is actually swallowed, and allows me to weigh my critters prior to their meals and spot-clean their tanks at the same time.
There may be other reasons that it's better, but it's Saturday on a holiday weekend and right now it would probably take me an hour and a half to watch 60 Minutes!
Just sayin.
