Why did my ball python regurgitate its meal?
A ball python regurgitates when it can't safely digest a meal, most often because the warm spot is too cool, it was handled too soon after feeding, or the prey was too large. It's stressful for the snake, so rest it for 10–14 days and re-feed something smaller; repeated regurgitation is a genuine health matter.
Regurgitation vs vomiting
There's a real distinction. Regurgitation is bringing a meal back up within a day or two, before real digestion begins, so it comes up looking largely whole. Vomiting is expelling a partly-digested meal days later and is more often a sign of illness. Either way the snake has lost the meal and is under strain, the causes below cover the common regurgitation triggers.
Temperature and prey size
The most common cause is a warm spot too cool to digest, a ball python needs about 31–32°C (88–90°F) on the warm side to break a meal down, and if it's drifted cool the food sits, spoils and comes back up. Prey that's too large (wider than the snake's thickest point) is the other frequent culprit. Check the warm spot with a digital probe before offering food again.
Handling and stress
Handling a ball python too soon after a meal is a classic trigger, leave it completely alone for at least 48 hours after feeding so digestion can get going undisturbed. General stress from a too-open enclosure, over-handling, or a recent move can also cause a snake to bring food back up. Feed in the evening, then give the snake quiet and darkness.
How to recover after a regurgitation
Bringing a meal back up strips the gut lining and its acid, so don't re-feed straight away. Rest the snake for 10–14 days with no food, fix whatever caused it (usually temperature), then offer a meal noticeably smaller than usual. Make sure fresh water is available throughout. Build the prey size back up gradually over the next couple of feeds once it's holding food down.
When to see a vet
See an exotics vet if a ball python regurgitates more than once despite correct temperatures and prey size, if it brings up a partly-digested meal days later (true vomiting), or if regurgitation comes with weight loss, lethargy, or mucus, repeated regurgitation points to infection or another underlying illness.
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 ball python, before it becomes a problem.

What causes a ball python to regurgitate?+
Usually a warm spot too cool to digest, handling too soon after feeding, or prey that was too large, occasionally illness. Regurgitation happens within a day or two of the meal, before real digestion begins.
How long should I wait to feed after a regurgitation?+
Rest the snake for 10–14 days with no food so the gut can recover, fix the cause (usually temperature), then offer a meal smaller than normal. Build the size back up gradually over the next couple of feeds.
What's the difference between regurgitation and vomiting in snakes?+
Regurgitation brings a mostly-whole meal back up within a day or two, before digestion starts, and is usually husbandry-related. Vomiting expels a partly-digested meal days later and more often signals illness needing a vet.
Is regurgitation dangerous for a ball python?+
A single regurgitation from a fixable cause like a cool warm-spot is manageable with rest and a smaller re-feed. Repeated regurgitation is serious, it strips the gut and points to an underlying problem, so see an exotics vet.
