The pickies....two of my biggest girls are on and off eaters, one of my normals has always been pretty picky, and my spider will only eat mice. My new little Pin girl and one of my big girls will only take live though. Makes them picky in my book since I pretty much only feed f/t.
The garbage disposals: all my colubrids and bull snake, all my boas, my Angolans, Bloods, and most of my newest younger BPs are strong eaters too. My little coastal has never refused a pinky/fuzzy rat and my retic will eat only if she's not in shed.
Overall: I'm pretty lucky to have some good eaters.
