How long do you wait to handle bp after feeding

[Don]

One of my girls regurged 4 days after feeding.

That is exceeding by double what the longest suggested wait here that has posted! I do not think that the regurg was from handling, unless you were rough or over handling. I've handled snakes right after eating to clean their cage. When I say handling, I mean short periods of around 20 minutes up to maybe an hour. Normally, I do like I said and give them the rest of that evening to digest. If you had a regurg after 4 days, I'd check the temps. It sounds like the snake did not get warm enough to digest.
