Ball Python regurgitated 2 days after eating, and is barely responding

It sounds to me that she was not warm enough to digest the rat, & also, after a snake has not eaten for so long a time, it would be best to feed on the small side.

Please don't rely on "feeling by hand" for temperatures...you need accurate measurements. We are roughly 98.6* which is way TOO hot for a BP, & their optimal temps. typically feel "cool" for that reason, but check!

BPs need about 88-90* in part of their cage to digest & properly regulate their body for optimal health. Even though you may have gotten away with 80* for some years, your BP isn't thriving this way, & this puts her
at risk of various illnesses.

Regurgitation can be very hard on a snake's insides: think about those rat teeth & claws that could cause internal lacerations...snakes have occasionally died just from regurgitating a meal, so it's best avoided by making
sure your snake is warm enough to digest & not fed something that is too challenging if they haven't eaten for a while and/or if their cage is too cool. I suspect that pain may have caused her to stiffen up. (it would me!)

Don't offer any food for 2-3 weeks after a regurgitation, & when you do, make SURE it's something small (!) & it would also be best to add some probiotic* powder (for snakes) to it also. (*BeneBac for reptiles, etc)

Alright, I ordered an infrared thermometer so I can get an exact temperature for her hot spot, as well as a higher wattage bulb to increase the temperature. I've been cautious about giving small meals ever since she ran into problems when she was younger from her meals being too small. But maybe these rats are too big. I'll try something smaller next time. Hopefully between that and the higher temperature she will be able to eat with less trouble. Thanks for the help!

That's a start... Just remember snakes cannot make their own body heat needed to digest their food...they rely on the available heat in their environment (in the case of pets, they're stuck with whatever we provide).
Their metabolism will be slow if they're kept too cool, and that affects how well they can digest their prey. If kept warmer (good metabolism) your snake may have had no trouble digesting that rat...it's all relative to
their environmental warmth. (also stress can be a factor- obviously snakes may regurgitate if handled or frightened after eating too)
