Ball Python

Overview

Ball pythons (royal pythons) are modestly sized, easygoing snakes and among the most popular reptiles kept ¹². Most adults are 30 to 45 inches, rarely reaching five feet or a little more, and females outgrow males ¹⁴. They are not large constrictors: an adult fits comfortably in a standard reptile enclosure. They can live twenty to thirty years with good care, so plan for the long haul ².

Natural history

Ball pythons come from the grasslands and savannas of West and Central Africa, especially Ghana, Togo, Benin and Ivory Coast ¹². They shelter in burrows and termite mounds to shed and escape the heat, and they do well in farmland, where rodents are plentiful ². Wild balls eat mostly small rodents ². They are nocturnal ². In parts of their range, especially Ghana, they are revered and protected. Elsewhere they are collected for the meat, leather and pet trades ².

Enclosure

• Babies. A 10-gallon enclosure (about 12 × 20 in) or a ventilated tub. Many young balls feel more secure in smaller spaces ¹².
• Adults. A 20- to 30-gallon enclosure (about 15 × 36 in) works for life ¹. CEX encourages custom enclosures of at least 3 ft × 2 ft × 18 in, since bigger is better for adults ².
• Escape-proof. All ball python enclosures must lock securely ¹.
• Hides. Two snug hides, one warm and one cool, no more than about 50% bigger than the snake. Make one a humid hide with damp sphagnum ¹.
• Enrichment. Low branches, dried leaves or hay for new scents, and an occasional rearrangement of décor ².
• Water. A sturdy bowl big enough to climb into ¹.

Temperature & lighting

Heat with an under-tank mat, radiant heat panel or ceramic emitter, always on a thermostat. Uncontrolled heat pads cause serious belly burns ¹². Never use hot rocks ¹.

UVB is not essential, but full-spectrum lighting with a low (2–5%) UVB output for 10 to 12 hours a day can help regulate daily rhythms ¹².

Humidity

Keep humidity at 50 to 70%. Ball pythons do poorly in dry air. Raise it to about 70% during a shed so the skin and eye caps come off cleanly ¹².

Substrate

Cypress mulch, coco fiber or coconut husk hold humidity well. Aspen or newspaper work if you watch humidity ¹². Never use pine or cedar, whose aromatic oils irritate snakes ². Spot-clean promptly, and replace all substrate at least every two months ¹.

Diet & supplementation

• Prey. Appropriately sized mice or small rats, no wider than the snake's widest point ¹².
• How often. Weekly for young snakes, every one to three weeks for adults. Ball pythons become obese easily ¹².
• Pre-killed only. Frozen-thawed prey is safest. Live rodents can injure or kill a snake, so never leave one unattended with live prey ¹².
• Supplements. None are needed when feeding whole prey ¹.

Fasting is normal. Healthy adult males often stop eating from about October to February ¹. Weigh your snake. Losing more than 10% of body weight means it is time for a vet visit ¹.

Handling & temperament

Ball pythons are named for their habit of curling into a tight ball, and their easygoing temperament is a big part of their popularity ²³. Socialized balls are often friendly with their families ³. Avoid handling right after a meal, since handling after feeding is a common cause of regurgitation ². Wash your hands after handling or feeding: reptiles and frozen feeder rodents can both carry Salmonella ⁹.

Health

Common issues

• Respiratory infections. Wheezing, open-mouth breathing and mucus are common in snakes. Low temperatures and dirty enclosures predispose snakes to them ²⁷.
• Regurgitation from wrong temperatures, overfeeding or handling after a meal ².
• Snake mites, tiny black mites that can spread between enclosures in the same room ²⁸.
• Intestinal parasites, especially in imported animals. An annual fecal exam is recommended ².
• Stuck shed and retained eye caps in low humidity ².
• Burns from heat pads without a thermostat ².
• Obesity ¹.

When to see a vet

See a reptile vet for weight loss of more than 10%, wheezing or mouth discharge, lumps, loose stools or repeated stuck sheds ¹². Get help right away for burns ², and treat open-mouth breathing or an unresponsive snake as an emergency ¹⁰. Quarantine new snakes for three to six months before they join a collection ².

Breeding overview

Ball pythons mature at two to four years when well fed ². Breeders usually cycle them in autumn with slightly cooler nights, and females typically lay six or seven eggs ². Sexing by probing should be done by an experienced keeper or a vet, because poor technique causes injury ².

Genetics & morphs

Selective breeding has produced many color and pattern morphs, including pieds, albinos, cinnamons, clowns and bananas ¹². Morph prices range from about the cost of a normal ball to several thousand dollars for rare combinations ³.

The spider morph has a known welfare problem. In a 2022 study, every spider morph snake examined had the "wobble" condition (head twisting, impaired movement, trouble striking and constricting), associated with malformed inner-ear balance organs ⁵. Novel Fauna does not recommend producing spider or spider-combination morphs.

Legal & ethics

Python regius is listed on CITES Appendix II, so international trade needs export permits ⁶. Many ball pythons are still exported from West Africa, and wild-caught animals usually carry heavy parasite loads ¹². Choose captive-bred snakes.
