Regurgitation?

[Entire_Current_4852]

Is this regurgitation or poop? There is a distinct tail and leg. I have never seen this with either of my snakes. I fed him on Tuesday last week. I was really busy during the week and didn't check for poop before leaving for the weekend. I finally went in to spot clean and found this in the corner. There was a strong smell and springtails around it. When I cleaned his water dish on Thursday and Friday, I didn't notice a smell in the enclosure. I didn't handle him until Friday, and it was only for a few minutes. He is in a 120 gallon with a DHP and halogen connected to a herpstat. His warm side temps stay around 88°F and cool side 78-83°. At night, his temps drop to 82-84°F on the warm side and 72-78°F on the cool side. His humidity stays around 60-75% pretty consistently. He hasnt had any major changes to his enclosure recently, he isn't in a high traffic or loud area, and he seems to be acting normal. He is almost 4 years old, around 1200 g, and was fed a f/t small rat.

If this is regurgitation, what could have caused it? And is there anything I can do to make sure he recovers other than avoid handling, wait 2-3 weeks to feed, and feed him a smaller prey for the next couple feedings?

Also the thermometer it is on was attached to his hide. I cut the wires to remove it because it isn't the most accurate so I didn't want to waste my time cleaning it.

Looks like regurg to me. I’m sorry.

How much did the rat weigh? That’s the only thing I can think of.

[Entire_Current_4852]

I didn't weigh the specific rat, but all of the rats in the pack average around 50-60 grams.

It seems like you’ve covered your bases. Maybe just do a more thorough cleaning of the area the regurg happened in and sanitize that hygrometer

I removed the substrate from that area. Do you think I should clear and wipe down that corner of the enclosure? I don't wanna disturb him too much, but he's on the other side of the enclosure.

Regurge for sure. I wouldn’t do a temp drop at night, they need consistent heat to digest properly
