Overview

What is this animal?

  • Children's pythons are small Australian pythons named after the naturalist John George Children, not after suitability for children.
  • They stay under about 39 inches and adapt well to captivity, making them one of the more manageable pythons.
  • Hardy, long-lived, and even-tempered, they suit those wanting a smaller constrictor.
  • Captive-bred animals are widely available and they tolerate a reasonable range of conditions.

Temperament

  • Children's pythons are generally placid and tolerate regular handling, becoming calm and easy to manage as adults.
  • Hatchlings can be nippy and food-driven but settle with gentle, consistent contact.
Show 2 more
  • They have a strong feeding response, so wash your hands and use tongs at mealtimes.
  • Being nocturnal, they are more active in the evening, but most adapt well to daytime handling once used to their keeper.

A good fit for

  • Beginners wanting a small python
  • Keepers seeking a long-lived pet
  • Those wanting a python that fits a 4 ft enclosure
  • People wanting a hardy, even-tempered snake

Common mistakes to avoid

  • Strong feeding response when young
  • Decades-long commitment - plan ahead
  • Low humidity causes shedding problems
  • Name does not mean ideal for children

Enclosure

Minimum 5.5 sq ft of floor · 39 x 20 x 30 in

Must be housed alone. Solitary

  • An adult needs a vivarium at least as long as the snake, half as wide and three quarters as tall: at least 39 x 20 x 30 in for a 39-inch adult, which a standard 4 x 2 ft enclosure at least 2.5 ft tall meets.
  • Give it good ventilation and a secure lid; larger is better.
  • Provide a hide at each end, a sturdy branch for occasional climbing, and a substrate such as aspen, cypress mulch, or coir.
Show 3 more
  • Maintain a basking area of 88-91°F and a cool side of 75-79°F using a thermostat.
  • Keep humidity around 50-60%, raised during sheds.
  • A modest nighttime temperature drop is natural and tolerated.

Care in depth

Diet

Carnivore - frozen/thawed rodents
  • Children's pythons are carnivores fed appropriately sized frozen-thawed rodents about as wide as the snake.
  • Hatchlings start on pinky mice; adults take adult mice or small rats every 7-14 days.
  • They are reliable feeders and often eager, so use tongs and feed in a controlled way.
  • As nocturnal hunters they may respond best to evening feeding.
  • Avoid overfeeding adults to maintain healthy body condition.

Health

Signs of good health, and the common problems
  • These pythons are hardy but can develop respiratory infections in cold or damp conditions and shedding problems if humidity is too low.
  • Their long lifespan means a multi-decade commitment to consistent care.
  • Keep the enclosure clean, with correct temperatures and a humid hide during sheds.
  • Quarantine new arrivals and screen for mites.
  • Annual veterinary checks help monitor weight and condition over their long life.

Is this urgent?

5 warning signs and how fast to act, 2 of them right away

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. Most snakes have only one working lung, and even boas and pythons, whose second lung is much smaller, have little reserve.
Now
Cannot right itself, or holds the head and neck in an unnatural twist (a western hognose that rolls over and plays dead when disturbed, then recovers once left alone, is showing normal defensive behaviour)Go now. Neurological signs are always urgent in a snake.
Now

Today

Retained 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.
Today

Soon

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.
Check today
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 first

This 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.

Bedding and substrate

5 safe, 1 with a caveat, 2 to avoid

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.
safe
Aspen shavingsThe classic for colubrids. Excellent for burrowing; replace any patch that gets wet.
safe
Topsoil and coco fibre mixBioactive-ready and holds a burrow.
safe
Sand-topsoil mixFor arid and sandy-soil burrowers such as hognoses: plain topsoil with some play sand mixed in holds a burrow. Keep it dry.
safe
Paper towel or newspaperQuarantine, feeding response problems, and post-surgery.
safe

With a caveat

Aspen in a high-humidity setupIt moulds. Aspen suits dry-side species; wet species need mulch or soil.
with a caveat

Never

Pine and cedarThe same aromatic oils that make them unsafe in small-mammal bedding.
never
Pure loose sand for species from humid habitatsIt holds little moisture, which makes shed problems more likely, and it does not hold a burrow. A soil mix with some sand is fine for snakes from sandy, dry habitats such as hognoses and sand and rosy boas.
never

Stuck shed and retained eyecaps are usually a humidity failure during the blue phase, not a substrate failure afterwards.

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

Minimum 5.5 sq ft of floor · 39 x 20 x 30 in

Every figure, and where it comes from

Sized for a 39-inch adult, the top of the usual range: at least as long as the snake and half as wide, with three quarters of its length in height, as Swiss law and the German expert report ask for small pythons. A standard 4 x 2 ft enclosure at least 2.5 ft tall meets it.

Minimum floor area5.5 sq ft of continuous, unbroken floor
As dimensions39 x 20 x 30 in
Height30 in minimum. This species climbs, so height is not optional.
CompanyMust be housed alone. Solitary
The recognised standards do not agree on this one
ReptiFiles (its body-length rule for snakes): 39 x 20 in of floor for a 39-inch adult: as long as the snake and half as wide. The floor area this site uses. ReptiFiles has no children's python care sheet; this is the rule its boa and sand boa sheets give, and it strongly recommends going larger. Checked 2026-10-23.
German expert report on minimum requirements for keeping reptiles (BMEL, 1997): Three quarters of the snake's length by half its length by three quarters of its length, for one or two, for Liasis, the genus children's pythons were then placed in: 30 x 20 x 30 in for a 39-inch snake. A minimum standard. The height this site uses follows its height rule. Checked 2026-10-23.
Swiss legal minimum (Tierschutzverordnung, Anhang 2, Tabelle 5, row 43a: small and medium-sized pythons and boas): As long as the snake, half its length wide and three quarters of its length high, for one or two: 39 x 20 x 30 in for a 39-inch snake. A legal minimum, recorded for context. The figure used here meets it for a children's python of up to 39 in. Checked 2026-10-23.
Currumbin Vet Services (Queensland, Australia): 35 x 18 x 16 in minimum. A veterinary minimum, below the figure used here. Checked 2026-10-23.
Austrian legal minimum (2. Tierhaltungsverordnung, Anlage 3): 5.5 sq ft of floor and 16 in of height for one or two adults (Liasis childreni). A legal minimum, recorded for context. The figure used here gives as much floor and more height. Checked 2026-10-23.

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.

Can a Children's Python eat that?

Everyday foods (1)

Frozen-thawed rodentsThe whole diet for these snakes. Choose prey no wider than the snake at its thickest point. Thaw fully in the fridge, then warm in a sealed bag to about 100°F and offer with tongs. One prey item per feed, at the interval in the species guide.
everyday food

That food is not on our list. A snake eats whole prey and nothing else, so if it is not a correctly sized prey item from the species guide, leave it out.

Whole prey is a complete food: snakes fed whole rodents need no supplement dusting.
