There is zero difference feeding inside the tub or outside the tub for most. It's honestly just a matter of what you are comfortable with. I've been snapped at by all sorts of snakes, for all sorts of reasons.

For those saying a snake won't bite if you don't smell like rodent - you are extremely bad at observing snake behavior. Clearly a snake could never associate a cage with a possible feeding, or mix up the hand with a possible food item. Fact is- snakes are pretty dumb, and sometimes they seem to screw up, who knows what stimulus does it.

The idea that the snake is aggressive, or cage aggressive because of it is 100% ridiculous, especially if it's only happened once or twice for the animal.
