What kind of animal is this from?
When was it last fed and what was it fed?
a corn snake, and I fed him yesterday.
I fed him a hopper mouse.
How are the temps in the enclosure?
With that soon of a regurge, I would expect it to be a little more noticeable as a rodent.
This is most likely a defecation. It looks a bit more fatty than usually passed. Stress if this is a new snake to you can sometimes cause this. Or being fed a very full pinky because of the lack of fur and the milk. Like a rat pinky for example since it’s around the size of the hopper, but more fat and less fur and bone.
Another cause could be a bacterial infection so do keep an eye on stools and behavior. If anything seems off, you may need a vet to prescribe antibiotics.
Gonna tag a couple of the colubrid gurus in case they think something else can be going on.
I really don’t think this is a regurgitation. I’ve seen “stools” that look like this occasionally.
Did you dispose of it already @vinnygoat? If not I would put it in a baggie and refrigerate it in case a vet visit if needed….
Edit to add “from my own corns”
Yeah, it’s not regurge. I call this “winter poop” because that’s when I see it most often, probably due to a corn hanging out in an area too cool for optimal digestion. I never worry about it beyond making sure the corn has access to good digestive temps. 
okay! thank you, this makes sense. i always feed him on the cool side of his tank so maybe that has something too do with it. i’ll make sure its getting warmer.
I think he may still be a little too small for hoppers, so i think trying rat pinky’s or going back down too feeding him fuzzies.
i’ll keep a close eye on him, he’s still relatively new, i’ve only had him for about a few months. he’s also still pretty shy so he hides often.
this is him for reference
Wow he’s a stunner! Thank you for the pictures and keep us posted! Remember that proper temps are critical for digestion…
I’m another voice saying that’s not a regurge. If your snake had regurged within 36 hours of feeding, the prey would still have been recognizable. It does look like poorly digested waste.
What are the temps in your enclosure?
You have an adorable snake, btw.
his warm side is 86 and his cool side is 75. his basking spot is 97.
okay! i will, thank you. and no i haven’t, i will keep it just in case.
I’d knock that basking spot back to 90F at the highest. Most adult corns won’t hang out in a basking spot much anyway.
Ouch! I would definitely dial back the 97 as Dean said. Also as he said, corns don’t bask typically. I would lower it even more. 87 or so……
Yeah, 97°F is wayyy too hot. That’s well into the range that can cause neurological damage. 86°F and 75°F are okay, though I don’t set any thermostats about 85°F, which is only for youngsters. Adults are set at 82.5°F. There is always a bit of variation when the thermostats cycle. You don’t want it cycling up from a high starting point.
It is actually possible to trigger regurges with temps that are too high as well as too low. It isn’t common but it can happen. The gut flora isn’t happy at those high temps, either.
How are you checking temps? Where specifically are these readings? (Under substrate, on top of substrate, inside hide, etc.)
