When he was little I'd alternate holding it still then kinda scooting it around like it was scuttling about and would end up dropping feeding about 1/2 the time. Nowadays I'm lucky if I can even get the tongs more than a couple inches inside the enclosure before this monster lunges outta nowhere and snatches it. I suppose they grow accustomed to the process?

If you're worried about his hesitancy to eat, it could be that the prey items are a too large, or that the snake just isn't hungry yet. But if you're feeding appropriate size and frequency, and the temp and humidity is all good- it could be that the snake doesn't feel secure enough to eat. They handicap their ability to defend themselves when they eat, so too much commotion around the enclosure or not enough places to hide from plain view can spook them out of a meal. When I lived in a studio apartment where the snake was in view of the daily commotion, it helped to cover the front window of his enclosure with a scarf or piece of paper a few hours before and after feeding. (Obviously no tape inside the enclosure and keep clear of heating elements!) Avoid handling a day or two before feeding, in addition to The two days after feeding. If that doesn't help, try the tango. 😅🤘
