My bp is only 200 grams and he refuses anything that is above a small mouse he won't eat medium or adult i have gotten him 2 times to eat mediums , he struck at a rat pup and spit it out he has some weird eating habits … i think he is scared of the bigger rodents, even tho they are still smaller then him in width, my new girl selene was on live mice the day after i got her i gave her a f/t rat pup gone in a second then i gave her another she eat them both she is the same weight as my other.. she is awesome eater and so was he when he was 100g now a few weeks later he can eat bigger and won't and sometimes he will strike miss and get discouraged and not strike again
