Overview
What is this animal?
- The ball python, from the grasslands and forests of West and Central Africa, is a heavy-bodied, docile snake named for its habit of curling into a tight ball when stressed.
- Calm and slow-moving, it is widely kept and bred in many morphs, but its humidity needs and tendency to refuse food make it a step up from a corn snake.
- Ball pythons are long-lived, frequently passing 25 years, so they are a multi-decade commitment.
- Their shy, security-seeking nature means they need plenty of cover.
- Well kept, they are gentle pets, but they are often mis-sold as effortless to nervous first-timers.
Temperament
- Ball pythons are among the most placid snakes, typically slow, gentle and tolerant of calm handling once they trust their environment.
- When frightened they tuck the head and ball up rather than bite, which is how they got their name.
- They suit keepers who want a relaxed, easily handled snake.
- They are solitary and must be housed alone.
- Cohabiting causes stress, hinders feeding monitoring and risks disease transmission and injury.
- There is no social need to meet, so individual housing is both simplest and best for their welfare.
A good fit for
- Keepers wanting a calm, handleable snake
- Those prepared for a 25+ year commitment
- People who can maintain steady humidity
- Owners patient with fussy feeders
Common mistakes to avoid
- Low humidity causing stuck shed
- Sparse enclosures causing stress and food refusal
- Panicking over normal winter fasts
- Feeding live prey
Enclosure
Minimum 7,200 cm² of floor (1,116 sq in) · 120 × 60 × 60 cm
Must be housed alone. Solitary; house singly
- Provide a secure vivarium of at least 120x60x60cm for an adult, with locking doors.
- Maintain a warm end of 30-32C and a cool end around 25-26C via a thermostatically controlled heat source, with a gentle nighttime drop.
- A low-output UVB tube is beneficial though optional.
- Humidity is important: keep it around 55-65%, rising during sheds, using a large water bowl, substrate moisture and good but not excessive ventilation.
- Ball pythons feel insecure in open space and need several tight hides and clutter such as branches and foliage; sparse setups cause chronic stress and feeding refusal.

Diet
- Ball pythons are carnivores fed appropriately sized frozen-thawed rodents, around the girth of the snake at its thickest.
- Thaw and warm prey thoroughly and offer with tongs; do not feed live, which risks serious bite injuries to the snake.
- Juveniles eat about weekly, adults every one to three weeks.
- This species is known for going off food for weeks or months, especially in winter, when stressed, or before shedding.
- In a healthy-weight adult a fast is usually not an emergency, but persistent refusal with weight loss needs a vet.
- Stable warmth, humidity and ample cover greatly improve feeding reliability.
Health
- Healthy ball pythons have firm muscle tone, clear eyes, clean nostrils and a complete shed.
- Low humidity causes retained shed and stuck eye caps, while overly wet, poorly ventilated setups cause scale rot and respiratory infections that produce wheezing or mucus bubbling.
- Maintaining correct humidity is the central husbandry skill.
- Watch for mites, mouth rot and obesity from over-feeding.
- Chronic refusal to eat alongside weight loss, or any open-mouth breathing, warrants an exotics vet.
- Because they live so long, budget for decades of care and possible veterinary costs.

Is this urgent?
Most snake worry is about feeding, and most feeding worry is misplaced. Check the guide for this species' normal fast before treating a refusal as illness.
Go now
Open-mouth breathing, bubbles at the nostrils, or an audible whistleGo now. Respiratory infection. Snakes have one functional lung and little reserve.
NowCannot right itself, or holds the head and neck in an unnatural twistGo now. Neurological signs are always urgent in a snake.
NowToday
A regurgitated mealDo not offer food again for at least a fortnight. Check the warm-end temperature today, then call if it happens twice. Usually too cold, handled too soon, or a meal too large. Repeated regurgitation is a different and more serious problem.
TodayRetained eyecaps after a shed, or a ring of stuck shed on the tail tipRaise humidity and provide a damp hide. Call if it is not resolved within a day. Almost always humidity that was too low during the blue phase. A constricting ring costs the tail tip.
TodaySoon
Refusing food for longer than is normal for this speciesLog the refusal and check the species guide. For an adult ball python, a fast of about a month is not in itself a cause for concern, and much longer voluntary fasts are documented. Weigh weekly through it. The weight trend, not the calendar, is what tells you whether a fast matters.
Log it firstThis is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a ball python eat that?
Reptile diets split hard by species. An insectivore and a grazing tortoise share almost nothing, so check the species guide as well as this list.
The full list
Never (15)
AlcoholNo safe amount at any body weight on this site.
neverAvocadoPersin. Fatal to many reptiles.
neverCaffeineCoffee, tea and energy drinks. Cardiac and neurological toxicity at tiny doses for an animal this size.
neverChocolateTheobromine and caffeine. Small mammals and reptiles cannot clear either.
neverCitrusToo acidic, and it interferes with calcium absorption.
neverDog or cat foodProtein and vitamin D levels formulated for a mammal. In tortoises it causes irreversible kidney and shell damage.
neverFirefliesLucibufagins. A single firefly has killed adult lizards. This is the most dangerous item on any reptile list and it is the one keepers do not know about.
neverFish caught from the wildThiaminase and parasite risk for turtles and aquatic species.
neverGarlicSame allium toxicity as onion, and more concentrated by weight.
neverIceberg lettuceWater with no nutrition. It fills a reptile up in place of food that would have done something.
neverLeekAllium family. Same mechanism as onion and garlic.
neverOnionOrganosulphur compounds damage red blood cells. The whole allium family is out.
neverRhubarbOxalate load high enough to cause acute kidney injury.
neverSalty or seasoned human foodSalt, oil and seasoning. Crisps, chips, seasoned leftovers and processed meat are all out.
neverWild-caught insectsPesticide residue and parasites, and the identification risk. Captive-bred feeders only.
neverRare treats (1)
WaxwormsVery fatty. Useful for a underweight animal or for medicating, addictive otherwise. One or two, rarely.
rare treatOccasional (5)
Bell pepperSafe, low oxalate, and the colour gets a refuser eating. A few small pieces a few times a week.
occasionalButternut squashWell tolerated and a useful source of vitamin A precursors. Small cubes a few times a week.
occasionalKaleGood calcium, mild goitrogen. Rotate it. Twice a week.
occasionalMealwormsHard chitin shell and a poor calcium ratio. Fine as part of a varied feed, poor as the whole diet. A few, alongside better feeders.
occasionalSpinachOxalates bind dietary calcium, which is the last thing a reptile at risk of metabolic bone disease needs. A very small amount, rarely.
occasionalEveryday foods (6)
Black soldier fly larvaeUnusually high in calcium; one of the few feeders that does not need dusting. Several per feed.
everyday foodCollard greensOne of the best staple greens for herbivorous and omnivorous reptiles. Daily.
everyday foodCricketsA standard feeder. Gut-load them for 24 hours before offering, or you are feeding an empty shell. Sized no wider than the space between the animal's eyes.
everyday foodDandelion greensExcellent calcium-to-phosphorus ratio and readily taken. Pick away from sprayed ground. Daily, for herbivorous species.
everyday foodDubia roachesBetter calcium ratio and more meat per insect than crickets, and they cannot climb glass. Sized to the animal.
everyday foodMustard greensGood calcium ratio; rotate with other greens. Several times a week.
everyday foodThat food is not on our list. Reptile diets are narrower than they look — check the species guide, and ask an exotics vet before offering anything unfamiliar.
Dust feeders with a calcium supplement to the schedule in the species guide. A reptile can be eating well and still be starving of calcium.
What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
Bedding and substrate
For snakes the substrate has to hold the right humidity for the shed, and let the animal get fully under it.
Safe
Cypress mulchHolds humidity without going sour quickly. A common default for tropical snakes.
safeAspen shavingsThe classic for colubrids. Excellent for burrowing; replace any patch that gets wet.
safeTopsoil and coco fibre mixBioactive-ready and holds a burrow.
safePaper towel or newspaperQuarantine, feeding response problems, and post-surgery.
safeWith a caveat
Aspen in a high-humidity setupIt moulds. Aspen suits dry-side species; wet species need mulch or soil.
with a caveatNever
Pine and cedarAromatic phenols.
neverSand for species that are not desert animalsAbrasive and dries the skin, causing shed problems.
neverStuck shed and retained eyecaps are usually a humidity failure during the blue phase, not a substrate failure afterwards.
