I've heard that feeding larger around prey items in lieu of multiple smaller prey is better because a snake's stomach can stretch in diameter, but not in length.

Is this species specific, or in general?

I ask, because I was watching videos of snakes eating other snakes, and in one of them, it looked like the python being eaten by the cobra was longer than the cobra was.

I feed my ballpython one prey item, and will probably always feed her one prey item instead of multiple smaller ones, but I got curious.

Any thoughts?
