I only have 2 ball pythons, and there are advantages to feeding outside a enclosure. It's cleaner and easer to keep an eye on live feed just to name a few. Also, the rats poop a ton when they're scared... you know, poopless, and I would rather that be in a box than in my pythons cage. Much easer to clean.
You don't need to attack me for my opinion. Like the FIRST POST said, it's a preference. I don't have 100 BPs and find feeding in boxes is much more convenient.
I took a quick video to help, It's funny how you twisted that and claimed I feed outside the enclose for show.
