The gentle noodle that curls into a perfect ball when shy!

Did you know? Ball pythons can go 3 to 6 months without eating (though they shouldn't have to). When scared, they curl into a tight ball to protect their head, hence the name!
The first week
The numbers a new owner needs in the first week, each from the article it links to. Rows with no link come from the encyclopedia.
- Legal check
- Broadly legal; the invasive-constrictor rules were written to exclude it. Illegal in Hawaii and New York City, a permit in New Jersey, Delaware and West Virginia, a permitted breeder in Minnesota, and city ordinances vary.Legal guide →
- Enclosure
- 4x2x2 feet for an adult, at least as long as the snake, in PVC, which holds humidity far better than glass. A hatchling up to about 300 grams does well in a 10-gallon, a juvenile under 3 feet in 36x18x18. One snake per enclosure.Setup guide →
- Temperatures
- Warm side 88 to 92°F with air nowhere above 95°F, cool side 75 to 80°F, nights 72 to 75°F. Every heat source on a thermostat, no hot rocks.Setup guide →
- Thermostat probe
- On the floor of the warm hide, the surface the snake lies on, held with a probe clip or suction cup rather than tape, never up in the air near the fixture.Heating guide →
- Humidity
- 55 to 65%, raised to 70 to 80% during a shed, on a digital hygrometer. Too dry means bad sheds and respiratory infection; too wet without ventilation means scale rot.Setup guide →
- Substrate
- Cypress mulch or coconut coir 3 to 4 inches deep. No aspen, which molds at this humidity, and never pine or cedar.Setup guide →
- Hides and water
- At least two snug hides, warm and cool, touching the body at several points, and a heavy bowl big enough to soak in.Setup guide →
- Cover
- Cork tubes and flats, leaf litter, and plant cover across the whole floor, so the snake can be out of its box without being exposed. A braced branch gets used.Enrichment guide →
- Feeding schedule
- Hatchlings every 5-7 days, juveniles at 6-18 months every 7-10, adults every 10-14, on prey the width of the snake's thickest point, fed inside the enclosure: a separate feeding tub adds stress and refusals.Feeding guide →
- Thawing
- In the refrigerator, or sealed in a bag in cool to lukewarm water. Never on the counter, never a microwave, and never fed cold.Feeding guide →
- Not eating
- A healthy adult goes 3-6 months without eating, with a seasonal dip from roughly October through March. Worry only with rapid weight loss, lethargy, mucus at the mouth, or wheezing.Feeding guide →
- Handling
- Nothing for the first one to two weeks or until it eats regularly. Then 2 to 3 sessions a week of 15 to 30 minutes, 48 to 72 hours after a meal, never during a shed.Handling guide →
- Weight checks
- Weigh monthly while growing. A rounded loaf in cross-section is right; a triangle with a ridge down the spine is underweight.Body condition guide →
- Budget
- $40 to $100 for a wild-type, $510 to $1,245 for the setup, $560 to $1,395 with the first vet exam, then $290 to $635 a year, about $20 to $55 a month.Cost guide →
- Adult size
- 3 to 5 feet, females significantly larger.
- Lifespan
- 20 to 30 years, up to 48 recorded in captivity.
- Quarantine
- 3 to 6 months, with a fecal exam before assuming it is healthy. Mites show within weeks; inclusion body disease can sit silent for months to years.Quarantine guide →
- Power outage
- 72-75°F is the cold floor. Below it for more than a day or two is the classic winter trigger for respiratory infection.Emergency plan →
Emergency card
Call the vet now if you see any of these.
- Any wheezing, open-mouth breathing, or visible mucus, this one is urgent
- Belly scale discoloration that's spreading or blistering
- Signs of mouth rot
- A prolapse (keep the area moist and get to a vet as soon as possible)
- Visible mites
- A female who turns weak, swollen or lethargic around laying time, or is past it and losing condition
- Sunken eyes and lethargy together, the sign of serious dehydration
A reptile-experienced vet, found before you need one. Respiratory infection needs vet-prescribed antibiotics, not a wait-and-see approach, and left untreated it can progress to pneumonia and become fatal.

Full Ball Python gear listFrequently Asked Questions
What humidity level does a ball python need?
Ambient 55 to 65%, raised to 70 to 80% while the snake is in shed. Dry air gives bad sheds and raises respiratory infection risk; too wet without ventilation goes the other way, toward scale rot.
Is it normal for a ball python to refuse food?
Yes. Ball pythons are famous for hunger strikes, and a snake in good body condition that turns down a meal or two isn't automatically an emergency. With temperature, humidity, and everything else checking out, offering again in a couple of weeks is often reasonable.
How long should I wait to handle after feeding?
48 to 72 hours. Picking a snake up on a full stomach is one of the most common ways keepers cause a regurgitation, and that is hard on the digestive system and slow to recover from.
