I'm still learning a lot-have had snakes only the last cpl of years but, the one point that was drilled into me was to feed in a different container. One reason was for subtrate issues (possible ingestion) and the other was (supposedly) to keep them from thinking your hand coming inside their area was "food" if they were used to eating in their housing. This has worked out really good for me because it makes me take the time to handle them by getting them out to feed, lol, and they know what the tubs mean

I feed mine f/t too but I give them only about 10 mins once they have completely fed and I can see that it's settled into their midsection. Then I move them back in their housing and leave them alone for a cpl of days.

I've never had either of them regurgitate and they usually head right for their hides too. Again, I'm fairly new at this but I don't see anything wrong with the way you mentioned you're doing now. Good luck
