Your ball python refuses dinner for the third week running. Maybe it’s pre-shed. Maybe it’s fasting. Or maybe something is wrong, and you won’t know which until you check.
Snakes hide illness by instinct. By the time a sick ball python looks obviously unwell, the problem has often been building for weeks. A wrinkled tail, a faint wheeze, or a 10% drop on the gram scale can signal trouble long before collapse does.
You’ll learn which signs are harmless quirks, which demand a reptile vet, and exactly where the line falls between them.

Key Takeaways
- Weigh your snake every week or two and log it, because a steady weight means a skipped meal is probably harmless, while a drop of more than 10% means you should call a vet.
- Check your temperatures first (31–32°C on the warm side, at least 24°C on the cool side), since cold causes sluggishness, food refusal, and the airway and mouth infections that follow.
- Don’t wait on wheezing, bubbles at the nostrils, open-mouth breathing, oral sores, neurological signs, or spreading skin damage, and skip home remedies because they can make things worse.
- Take your weight log, photos, and enclosure temperatures to a reptile-experienced vet, since most illness traces back to husbandry and catching it early makes treatment far easier.
Appetite Loss and Unexplained Weight Changes
Often, a ball python that skips a meal is simply being a ball python. Pre-shed fasting, seasonal fasting in adult males, and a new home can all shut down appetite for weeks. None of that’s alarming if your snake’s weight holds steady.
If your snake keeps refusing food past a few weeks, a ball python feeding schedule by age and size helps you judge what’s normal for your animal.
So weigh your snake. Use a gram scale, once every week or two, and write the number down. A Lack of Appetite with stable weight is usually normal. A drop of more than 10% isn’t, and neither is Severe Weight Loss paired with a refused meal.
Check your temperatures first. The warm side needs to sit at 31–32°C, because cool enclosures stall digestion and food refusal follows. Fix that, then watch for a week.
If weight keeps falling, call your vet. These are the diagnostic signs that matter most. Parasites, respiratory infection, and mouth rot all start this way. A reptile vet may recommend fecal analysis and bloodwork, and sometimes x-rays, to find the cause of a snake that refuses food and keeps losing weight.
Lethargy, Unresponsiveness, and Abnormal Movements
Cold is the usual culprit behind inactivity and lethargy. If your warm side drops below 31°C or the cool side below 24°C, metabolism slows and your snake just lies there. Fix the heat, then recheck in a day. A digital reptile thermometer with probe lets you check both ends of the enclosure accurately, since stick-on dial gauges often read several degrees off.
Constipation or impaction can look identical. Watch for missed feces and urates.
Poor coordination is a different problem. Head tremors, corkscrewing, stargazing, and a snake that can’t right itself point to a neurological issue. Spider morphs often carry a lifelong wobble, but new or worsening signs aren’t wobble. Abnormal posture or tremors after a heat burn deserve the same scrutiny.
Don’t wait on these. Unresponsiveness, unsteady movement, or any neurological sign alongside other symptoms means you should call a reptile vet today.
Noisy Breathing, Mouth Discharge, and Oral Sores
Cold doesn’t just slow your snake down. It also invites infection. When temperatures slip, bacteria move into the airways and mouth, so noisy breathing often follows a heating problem.
If you’re unsure whether a sound is a harmless warning or a sign of illness, this guide on why ball pythons hiss and what it means helps you tell the difference.
Listen closely. Wheezing, clicking, or whistling means mucus is blocking the airways. Look for open-mouth breathing and bubbles around nostrils, which signal a developing respiratory infection. Gurgling or rattling means fluid has built up, and that’s serious.
Check the mouth too. Swollen or bleeding gums with yellow or white pus are stomatitis, or mouth rot. Snakes with sore mouths refuse food.
Don’t try home remedies. They risk aspiration and worsen infection. Any wheezing, gaping, or discharge needs a veterinarian within 48 hours. Oral sores with pus or bleeding need one today.
Skin Problems, Mites, and Stuck Shed
Your ball python’s skin tells you a lot about its health, and problems there often show up before anything else does. Check the three issues below against what you’re seeing in the enclosure. Catch them early, and most are far easier to treat.
Scale Rot and Skin Lesions
Scale rot spreads like a stain through wet cardboard, quietly and fast. Check your ball python’s belly weekly. Choosing a breathable ball python substrate that dries quickly between spot-cleanings keeps your snake’s belly off soggy bedding.
Scale rot spreads quietly and fast like a stain through wet cardboard, so check your ball python’s belly every week
Look for:
- Pink, brown, or yellow patches
- Blisters that weep fluid
- Crusty, lifting scales
- A foul smell
- Painful ulcers that won’t heal
Don’t wait. This skin infection worsens daily, so call a reptile vet. Fix damp substrate and shedding problems as well.
Snake Mites and Persistent Soaking
Why is your ball python parked in its water bowl for hours? Sometimes it’s temperature or hydration, but snake mites, specifically Ophionyssus natricis, are a common culprit. Look for tiny moving specks around the eyes, lips, and chin, plus rubbing and restlessness. Soaking alone proves nothing. If you spot these signs, book veterinary care.
Mites hide in your enclosure too.
Retained Shed and Eye Caps
How can you tell a normal shed from dysecdysis? Check the whole snake.
Stuck shed often hangs on at the tail tip, toes, and head. Look closely at the eyes, too.
A retained eye cap leaves the eye hazy after shedding.
Don’t pick at it. You can injure the eye. Call your vet if skin constricts toes or eye caps stay.
Dehydration, Abnormal Droppings, and Body Swelling
Imagine this: you lift the lid and find your ball python’s tail skin wrinkled, with a dry, crumbly dropping in the corner. Sound familiar? That’s dehydration talking, and it usually traces back to humidity below 70%.
Check for these signs:
- Skin that stays tented when you gently pinch it
- Dented eye caps or a silvery haze over the eyes
- Abnormal droppings: dry and clumpy, runny, or white with a foul smell
Blood in a stool needs a vet, not guesswork.
Watch for swelling of the body, too, especially near the vent. A soft, puffy belly or tissue poking from the cloaca means immediate veterinary care. Abnormal posture, like holding the body stiff or kinked, makes it more urgent.
Mild cases? Raise humidity and offer an electrolyte bath at 82-84°F.
A shallow, snake-safe reptile soaking tub makes electrolyte baths easier, since your ball python can rest its chin above the water while it soaks.
When Your Ball Python Needs Veterinary Care
Say your ball python has skipped two meals, and now you notice she’s lost 40 grams since last month. Maybe it’s shed. Maybe it isn’t.
That’s why regular health monitoring matters. A single missed meal isn’t an emergency, but a downward weight trend is a warning.
Go to the vet immediately if you see labored breathing, collapse, severe bleeding, or if your snake can’t move normally. Don’t wait to see if it passes.
Book a prompt visit with a reptile-experienced vet for wheezing, mouth lesions, unexplained weight loss, or skin problems that won’t clear up. Signs alone don’t confirm a diagnosis, and a vet can separate illness from husbandry mistakes. Bring your weight log, photos, and your enclosure’s temperature details.
Frequently Asked Questions (FAQs)
How to tell if a ball python is dying?
Your ball python hasn’t eaten in months, and now you can see her spine and ribs. That’s Severe Weight Loss, Lack of Appetite, Dehydration, Breathing Difficulties, and Abnormal Posture. Call a vet today.
What are the common causes of death in ball pythons?
Most ball python deaths trace back to husbandry. Poor heat and humidity cause respiratory infections and dysecdysis, while bad diet leads to metabolic bone disease. Cryptosporidiosis and inclusion body disease are incurable, so quarantine newcomers.
Will a snakes respiratory infection go away on its own?
No, a ball python’s respiratory infection almost never clears up on its own. Waiting lets it spread to the lungs. If you see open-mouth breathing or mucus at the nostrils, call a reptile vet today.
What’s the life expectancy for a ball python?
With solid care, your ball python can live 20 to 30 years, and some pass Wild snakes average 10 to Keep temperature, humidity, and feeding right, and watch for early signs of disease. Call your vet promptly.
What is the best way to treat a ball python for mites?
Mites can wreck your ball python overnight, so act at first signs.
See a vet for parasite control, since one oral fluralaner dose beats repeated spraying. Swap substrate for paper towels and scrub the enclosure.
What are the signs of a dying ball python?
A dying ball python stops eating for months, shows its spine, and can’t coil or strike. Watch for Breathing Difficulties, open-mouth gasping, and sunken eyes from Dehydration. Call an exotic vet immediately.
How often should ball pythons have bowel movements?
My ball python hasn’t pooped in weeks, so something’s wrong," is a common worry, but it’s usually not true. Most adults go every one to three weeks, about a week after eating. Past three weeks, call a vet.
Can stress alone cause a ball python illness?
One missed meal means little in a ball python; weight trend matters more. Stress alone doesn’t cause illness, but it weakens immunity. Don’t dismiss signs. Review environmental conditions, reptile stress management, then call a veterinarian.
What temperature range is safe for ball pythons?
Ball python temperature matters: keep the basking surface at 88-92°F and the cool side at 75-80°F. Proper temp regulation needs that gradient. Never let air exceed 95°F or nights drop below 65°F. Stable conditions matter.
Do ball pythons need calcium or vitamin supplements?
My snake eats whole prey, so it’s covered." Mostly, yes. A healthy ball python on a quality ball python diet usually needs no routine supplements. Skip them unless your vet finds a gap, since excess D3 causes harm.
Conclusion
A snake coiled tight in a dim hide can look perfectly calm while something quietly goes wrong. Your job is to notice before it shows.
Learn the signs of a sick ball python, then weigh your snake monthly, check its breathing, skin, and droppings, and write everything down.
Harmless quirks pass. Real illness doesn’t. If your snake shows open-mouth breathing, bubbles, or sudden weight loss, call a reptile vet today. Waiting costs more than asking.
