I like to give my new snakes ample alone time when I aquire them. Whether they were shipped to me, or I picked them up from somewhere, I assume that they are confused or stressed by the experience, and I feel a lot better just leaving them in solitude so they can gather themselves and get comfortable in their new surroundings.
Usually when I aquire a snake it is on the weekend, when I usually am feeding, so they naturally won't be fed until the next weekend anyway. If I get one during the week from an online source I will either skip feeding the next weekend and end up waiting over a week, or try that coming up weekend... I tend to follow my gut instinct about the particular snake.
As far as handling after feeding... I really don't handle my snakes that often anyway, but if I do end up in a mood where I want to visit with one of them, I won't do it if it ate less than two days ago. I'd rather not risk a regurge... they are not pleasant or healthy for the snake.
As for handling on feeding day, like I said above, I don't take them out all that much other than for cleaning and the like, so this isn't a big thing for me either. There are some snakes that I would really rather not handle when I know they are hungry, so I stay clear of them until they have a prey item occupying their teeth.![]()
