I don’t handle any of my snakes on feeding day, even those not eating that day. While I’ve never had an issue with most my ball pythons, my boa is locked and loaded when she smells prey. Piper (pied bp) is an exception to the rest, she’s an eating machine and thinks everything coming in the cage is food. If rats/mice are thawing, I feel it’s better safe than sorry. As for hook training, yes, I hook train all my snakes. It prevents misunderstandings. The bp’s aren’t really big enough to really hurt, but I prefer to avoid bites when I can. Usually everyone is fine by the next day.
