Ball Python

Python regius

Small West African python that coils into a ball when worried, and the most-kept pet snake on earth.

The ball python conquered the world hobby by being everything a first snake should be: modest in size, reluctant to bite, slow-moving and undemanding — a hider that asks for warmth, privacy and a rat every week or two. The two things nobody warns buyers about are time and appetite: this is an animal that can see out thirty years, and a healthy adult will periodically refuse food for weeks or months with total composure while its keeper unravels. Provided the heat is right, the fast is usually the snake’s schedule, not a crisis.

Right for you if

You want a genuinely calm snake and can commit across decades.
Feeding whole prey — stored in your freezer — is a settled question for the household.
Exact heat, checked with a thermostat you trust, is your idea of routine.
A pet that hides most of the day suits you; the appeal is quiet, not spectacle.

Wrong for you if

A months-long fast would have you force-feeding or panic-buying equipment.
Anyone expects an interactive, active display animal.
The freezer rule fails at the first housemate veto.
You have not checked whether this species can be kept where you live — for this snake, in Australia, that check comes first.

Welfare and sourcing — read this part

Respiratory infections are common in reptiles and track unfavourable temperatures, poor sanitation and malnutrition¹ — and a snake’s enclosure is its entire climate. An ectotherm needs a real gradient, run on a thermostat, because it heals and digests with borrowed heat.²
Buy captive-bred from a breeder who shows you feeding records — date, prey, taken or refused. A ball python with a documented appetite is worth more than any morph premium.
Reptile keeping is licensed and restricted differently from place to place, including state by state within Australia — and for some species here that difference is the whole question. Check what applies where you live before you commit.

Disorders and Diseases of Reptiles. MSD Veterinary Manual 2026. Accessed 2026-09-05. International MSD Veterinary Manual Secondary nutritional hyperparathyroidism — metabolic bone disease — is the most common bone disease seen in pet reptiles, driven by poor calcium-to-phosphorus ratios, insufficient vitamin D3, lack of UVB light and inadequate temperature, and it predominantly affects rapidly growing plant- and insect-eating lizards, turtles and tortoises. Respiratory infections including pneumonia are common in reptiles and are tied to unfavourable temperatures, poor sanitation and malnutrition. Treatment does not succeed unless nutrition, environment and sanitation are corrected too.
Providing a Home for a Reptile. MSD Veterinary Manual 2026. Accessed 2026-09-05. International MSD Veterinary Manual Reptiles are ectotherms that regulate body temperature by moving around their environment, so an enclosure must offer a range of temperatures within the species’ preferred band — and exceeding the upper limit by only around 5°C can be deadly for some species. UVB light in the 290–320 nm range is essential in many species for making vitamin D3 in the skin, which enables dietary calcium absorption.
