i feed F/T to all 5 of my snakes and plan to for my entire growing collection until further notice.
i pull out food enough for everyone currently. When the weather starts to get colder i have one animal i know will probably go off feed.
Everyone is offered food, i can tell through behavior who will eat and who wont (i use a hair dryer to defrost, and within 10 seconds of the dryer being on EVERYONE who is hungry is cruising their enclosure for food). Currently, either of my two big females get any left overs, but once my Carpet python gets bigger they might have some competition for the title of "garbage disposal" for the left overs.
