We were told at the pet store to feed ours in seperate container as well (by a woman who has had a BP for 3 years) but after reading all the comments here, and watching our snake eat several times now, I can't imagine moving her some where else to feed her.

First of all, as soon as she smells the mouse, her behavior is completely different then any other time she's acted "cautious" when someone reaches in her tank (with the mouse, her tongue goes crazy and she starts searching for the mouse right away- we feed F/T)
Also, I would be more afraid to pick her up & move her after eating. She still seems a little to "fired up" and I wouldn't want to put my hand in there then. (nor risk moving her while digesting- some here have said, just slight noises have made their snakes reguritate their food)

Finally, there has been a few times our snake did not eat right away. She wanted it dark in her tank, and she just hung out, hovering over the mouse. If she wasn't in her tank, im not sure how I would have managed to get her back in, in that mood.

Granted we've only had our snake a few months- we have fed every meal in the tank. She goes in her hide right after. We Leave her alone a couple of days to digest, except changing water, etc. Then get her out for 10min. to 1/2 hr. (they say start with only 5-10 min. in beginning) pretty much every day, until its feeding day again. She hasn't shown any sign of our hand being food when we reach in.

Good luck- its been a fun learning process for me.
