It's not just the hatchlings that can come barreling out at meal time.This, combined with the fact that I have quite a few hungry mouths to feed, are the reasons that I don't feed anyone in a separate enclosure. This picture was from one of the first few feedings when I got this girl (no - this isn't normal - just an extreme example of a great feeding response). She is a such a sweetheart, but you'd better believe I'm going in her tub rat first on feeding day when the entire room has been scented with rats that have been thawing for several hours. I'm not saying this to scare anyone off from feeding in a separate enclosure - far from it. Many people do so successfully. I'm simply saying "know your audience".
Edit: I should add that I didn't let her stay there on her own. I lifted her up and back in her tub while she still had the rat wrapped tightly. Notice though, that when she flew out of the tub, she actually missed the rat with her mouth, but caught it with her body. Lets just say that knowing she was in feeding mode with her mouth still completely free made me take extra precaution while getting her back in her tub safely.
