Do you feed in tank?

A) A small hook doesn't cost any more than a separate tank.
B) Most ball pythons are fine unless it's near feeding day, regardless.
C) Some snakes will launch at you for food when they're hungry, no matter where you feed them.
D) A fairly large number of ball pythons either feed poorly (skipping meals), or won't feed at all, if put into a separate cage to do so.

All that in mind, my opinion is still--it's best to feed ball pythons in their own cage, where they are comfortable, as this is more important than our comfort, and doesn't pose much of an inconvenience, even if the snake does develop cage aggression. If you have a ball python, and feed it in a separate cage, and it eats every time when it's not in shed, then great...by all means, continue to do so. However, if you feed in a separate cage, and your ball python is a picky eater, it's time to think about changing things.
