Thankfully, I am extremely lucky to have two BPs who are fantastic eaters. Both ladies eat without problems, especially Tonks, who has never turned down prey and in fact the only eating problems she's had (wild striking, accidentally striking substrate) were from being a bit too eager. In fact, I offered Tonks her first rat last night, and she didn't even seem to notice it wasn't a mouse, just grabbed it and down it went. Ana Gwyn got her first non-white rat last night and again, didn't even notice. And Ana Gwyn seems to know that when I turn her hide over, it means food, and she starts looking for her rat. I would definitely be more hesitant to try the technique with picky eaters or sensitive snakes, but my girls don't have any of the typical BP eating issues.
