I actually had a pet store give me a hamster pinky free because some new moron employee sold the mom. My snake ate it no problem. And as far as the getting a taste for food items that aren't mice and then refusing everything as a result...for the longest time my snake wouldn't eat f/t anything [insert six-month saga here], so over a period of like two months I (mostly out of necessity) fed him a whole variety of food- pinky mice, fuzzy mice, pinky rats, pinky hamster (but all live). Then one day I tried again with the f/t thinking that maybe I'd trick him, since I was changing up his food so often that he'd just think of this as another menu change, and he ate the f/t mousie right up and has been eating f/t like a champ ever since. I'm sure plenty other people could tell you that they switched their snake's food around and it ended up costing them big time because the snake wouldn't eat mice after that, but the switching for me ended up being the best thing that happened to us.
