You are FAR more likely to get bit when you try to handle your snake after feeding him (to put him back in his regular home) since many snakes stay pumped up
in "feeding mode" for hours or even a day or more. It's stressful and distracting for snakes to be handled, even just to put them in another cage (to feed). May I
strongly suggest you feed him only in his own regular cage without any handling. There are easy ways for our snakes to tell it's NOT feeding time...it's FAR more
important to have a snake that's eating, ya? There are various reasons that BPs may refuse food, but you are making this much harder than it has to be.
And actually, since eating (& survival) is the main thing for our pet snakes, you really shouldn't be handling him at all until he's eating reliably for you. BPs have
their quirks & preferences, for sure, but feed him in his regular cage where he feels safer for best results.
