Why did my corn snake regurgitate its meal?
A corn snake that brings a meal back up within a day or two of eating has almost always been let down by its setup, most often a warm end too cool to digest, handling too soon after feeding, or a meal that was simply too large. It's a single regurgitation, corrected and rested, that's usually fine; repeated regurgitation is a vet matter.
A too-cool warm end is the usual cause
Digestion is entirely heat-driven, and this is the first thing to check. A corn snake needs a warm end of 28–30°C (82–86°F) to break a meal down, if it's drifted a few degrees cool, the snake can't process the prey and brings it back up before it rots inside. Measure at the basking surface with a digital probe rather than a stick-on dial, and confirm the thermostat hasn't slipped before feeding again.
Handling too soon, or prey too large
The other common triggers are mechanical. Handling a snake in the 48 hours after a meal can stress it into throwing the food back up, so leave it undisturbed while it digests. Prey that's too big is the other culprit, a meal wider than the snake's thickest point is hard to process and more likely to come back up, so size prey to the snake and don't over-feed.
Regurgitation versus vomiting
The timing tells you how worried to be. Regurgitation is bringing a meal up within roughly a day or two, before it's really been digested, usually a husbandry problem you can fix. Vomiting is a meal coming back up days later, part-digested and foul-smelling, and it's a more serious sign that can point to infection, parasites or illness. A part-digested meal returned after several days deserves a vet's attention rather than a simple setup tweak.
Rest, then feed smaller
After a regurgitation the gut is irritated and needs time. Wait 10–14 days before offering anything, then feed a noticeably smaller-than-usual meal so digestion has an easy job, and step the size back up gradually over the following feeds. Fix the warm end first so the snake can actually digest, keep handling to zero around feeding, and log the date and prey size, a pattern of repeated regurgitations is far easier to spot, and far more concerning, than a one-off.
When to see a vet
See an exotics vet if a corn snake regurgitates more than once despite a corrected warm end, if a meal comes back up days later part-digested and foul-smelling (vomiting rather than regurgitation), or if regurgitation comes with weight loss, lethargy, wheezing or abnormal stool, repeated regurgitation can point to infection or parasites and shouldn't be managed at home.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your corn snake, before it becomes a problem.

What's the difference between regurgitation and vomiting in a corn snake?+
Regurgitation is a meal brought up within a day or two, before it's digested, usually a temperature or handling problem. Vomiting is a part-digested, foul-smelling meal returned days later, which is more serious and warrants a vet.
How long should I wait to feed after my corn snake regurgitated?+
Rest the snake for 10–14 days to let the gut settle, then offer a smaller-than-usual meal and build the size back up gradually. Fix the warm end and avoid handling around feeding before you try again.
Can handling make my corn snake regurgitate?+
Yes. Handling in the 48 hours after a meal can stress a digesting snake into bringing it back up. Leave the snake undisturbed while it digests, and don't handle for at least two days after feeding.
My corn snake keeps regurgitating its food, what's wrong?+
Repeated regurgitation goes beyond a simple husbandry slip and can signal infection or parasites. Confirm the warm end holds 28–30°C (82–86°F), and if it keeps happening on a correct setup, see an exotics vet rather than continuing to re-feed.
