I feed once every 5-7 days. It varies depending on when I find the time to thaw and feed. Everyone gets fed on that schedule whether or not they've pooped (rarely have they not). At 146 grams I'd feed an adult mouse or a rat pup, depending on what I had available (e.g. today the choice was adult mouse or small rat because that's what I had on hand). I don't do live for many reasons - convenience, cost as frozen is cheaper to buy in bulk, and I thought a bp was going to eat the small rat, but he refused to even strike at it, so he got an adult mouse and one of the adult corns got the rat. If the corn didn't eat the rat either, what the heck would I do with a live rat? Take it back to the pet store? I'd much rather refreeze than return lol.
