Wow, he's really a food-focused snake. I think it's mostly the summer weather that makes snakes try to pack in the food before temperatures (in the wild) cool off.
My Aussie spotted python (very similar to Children's) is a very strong feeder too, but I don't have this problem with her. Personally, I use a little spray of cool
water to the face of snakes that act like Bender does...it hurts nothing but quickly "changes their channel", & while you might not want to do that with a shy snake,
that doesn't seem to apply here, lol. I'd be careful about putting a towel over a snake like this...some have been known to bite & even try to ingest such things, or
his teeth could get caught on it too. My spotted python is very strong when she holds on...I'm glad she's never tried to bite me while doing so...that's not a very
endearing quality, IMO. From your photo, he's not skinny either...if he had trouble keeping weight on, that would be a different thing, maybe parasites to blame.
I wish I knew why some snakes just seem to be this way...I hope you can get him to calm down. Over-feeding isn't a good answer either, health-wise. (btw, my
Aussie spotted is 11+ years old now)
