I read on your other thread that you jsut recently got your ball python. Don't attempt to feed it for one week starting from the day you got it. You are more likely to have a successful feeding if you wait the whole week.

I feed all my ball pythons in their home enlcosures. Most keepers do as well and there are a few who use a seperate container. Although, the snake is more likely to refuse food in a seperate container in my opinion.
