A woma or black-headed python needs more than a warm box and regular meals. The enclosure must let a strong, ground-dwelling snake move, hide and choose its own temperature, while making feeding and cleaning safe for both of you.
These Australian pythons share some care needs, but they are different species. Start with a setup matched to your snake, then use its weight, behaviour and shedding history to check whether that setup is working.
Quick Answer
Keep woma and black-headed pythons individually in secure, spacious enclosures with sheltered warm and cool areas, clean water and controlled heating. Feed appropriately sized, thawed whole prey on an individual schedule, and avoid handling for three days afterwards. Food refusal needs assessment in context, but breathing difficulty, serious burns or marked weakness require urgent veterinary care.
How are womas and black-headed pythons different?
| Species | Natural history | What this means at home |
|---|---|---|
| Woma python, Aspidites ramsayi | A banded python associated with sandy, arid habitats. NSW records describe an average length around 1.5 metres, with larger individuals reaching 2.7 metres. | Provide generous floor space and sheltered routes. Plan the adult enclosure around the individual, not a small juvenile's size. |
| Black-headed python, Aspidites melanocephalus | A northern Australian python found in savanna, scrub and other habitats. It uses burrows and sheltered retreats; it is not exclusively a desert species. | Provide substantial ground-level cover and a climate plan matched to the species and its background. Do not assume extremely dry conditions are always suitable. |
These differences are described in the NSW woma species profile and the Smithsonian's black-headed python account. Both are non-venomous, but a feeding strike or a bite from a frightened snake can still cause injury.
Before acquiring either species, check your local wildlife authority's permitted-species list, licence conditions and recordkeeping requirements. For example, NSW reptile keeper licensing depends on the animal and licence type. Obtain a legally sourced, captive-bred snake with identification and feeding records.
What enclosure does an adult python need?
Choose space that allows the snake to stretch out fully and move between distinct areas. A fixed 120 cm enclosure is not an adequate lifetime recommendation for every adult. Research on captive corn snakes found that access to larger enclosures allowed more natural behaviour, supporting full-length stretching as a welfare design principle rather than treating legal minima as an ideal. See the enclosure size and snake welfare study.
- Use escape-resistant doors, secure locks and ventilation openings the snake cannot squeeze through.
- Offer snug hides at both ends, plus covered routes between them. A snake should not have to choose between feeling safe and reaching a suitable temperature.
- Provide a stable water bowl, low climbing opportunities and securely supported furnishings. Heavy rocks or logs must not collapse when the snake pushes or burrows beneath them.
- Choose clean, low-dust substrate suitable for the enclosure's moisture requirements. Plain paper is useful during initial health monitoring because waste and mites are easier to see.
House pet snakes separately. Sharing creates avoidable competition and feeding risks, particularly in species whose wild diets include other reptiles. Separate housing also makes it clear which snake ate, shed or passed abnormal waste.
How should you manage heat, humidity and lighting?
A thermostat controls the heater; separate thermometers tell you what the snake actually experiences. Provide a measured gradient, guard heating equipment and avoid hot rocks. Keep ventilation open. Excessively dry conditions and persistently wet bedding can both cause problems. The MSD Veterinary Manual's reptile husbandry guidance explains these principles.
Before bringing the snake home, obtain a written species-specific plan from a reptile veterinarian or an experienced keeper working with that veterinarian. It should distinguish basking surface temperature, warm-hide air temperature, cool-end temperature, overnight limits and humidity. These are different measurements; a single number on a heat controller cannot replace them.
Check the empty enclosure through complete daytime and overnight cycles. Record readings at the locations the snake can reach, including beneath a hide. Review them again after changing the room heating, substrate depth or equipment.
Provide a regular day and night cycle with darkness overnight. Discuss appropriate UVB exposure and shaded retreats as part of the lighting plan. A bulb's percentage label alone does not describe the exposure reaching the animal. Do not place the enclosure in direct window sunlight, where it can overheat; the RSPCA's enclosure-location guidance explains why room placement matters.
What should you feed them?
For an established rodent-feeding python, use appropriately sized whole prey from a reliable source, thawed completely and warmed before offering with feeding tongs. Ask for the snake's existing prey size and feeding history. Do not introduce wild-caught lizards or snakes as enrichment.
There is no universal weekly ration for both species at every age. Growing juveniles, lean adults and overweight adults need different plans. Choose meal size and spacing with your reptile veterinarian, using weight and body condition rather than an enthusiastic feeding response alone.
Live rodents can seriously injure a snake. Leave the snake undisturbed for three days after feeding to reduce regurgitation risk, and do not force-feed at home. These precautions are supported by the MSD Veterinary Manual's snake nutrition guidance.
How worried should you be about a change?
| Observation | Possible significance | What to do |
|---|---|---|
| One declined meal in an alert adult with stable weight and normal breathing | Shedding, disturbance or seasonal changes may contribute. | Check the environment and feeding record now. Avoid repeated daily offers and contact your reptile vet if refusal continues or this differs from the snake's usual pattern. |
| Repeated refusal, weight loss, regurgitation, retained shed or a new skin lesion | Husbandry problems, parasites, infection or another illness need consideration. | Contact a reptile vet promptly for triage. A young, thin or recently ill snake needs earlier assessment than a healthy adult. |
| Laboured breathing, collapse, a significant burn or uncontrolled bleeding | Potentially life-threatening illness or injury. | Arrange emergency veterinary care immediately. |
What else could explain the signs?
Food refusal is a sign, not a diagnosis. A vet will consider temperature, recent handling, prey changes and shedding alongside oral disease, parasites and internal illness. Regurgitation can follow a husbandry problem, but repeated episodes must not be dismissed as a feeding mistake. The Merck guide to reptile disorders describes important medical causes.
Red, blistered or damaged belly scales may involve infection or thermal injury. Wheezing, mucus and increased breathing effort require assessment rather than simply increasing enclosure humidity. Depending on the findings, examination may be followed by faecal testing, imaging or samples for infection testing. See MSD's guidance on reptile skin and respiratory disease.
When is this an emergency?
Call an emergency clinic immediately for sustained open-mouth or laboured breathing, collapse, severe weakness, major injury or a significant burn. Ask whether the clinic can receive reptiles and follow its transport instructions. Use a secure, ventilated container, minimise handling and prevent direct contact with a heat pack or hot-water bottle. Do not force food, water or medication into the mouth.
What should you do next?
- Check today's essentials: locks, water, heater function, warm and cool readings, and visible waste.
- Keep a simple record: meals, refusals, shedding, droppings, weight and unusual behaviour. Bring enclosure photographs and actual measurements to a veterinary appointment.
- Handle on the snake's terms: support the body and keep early sessions brief. Stop if the snake repeatedly tries to escape, hisses or strikes. Get practical instruction before handling a large or reactive individual.
- Act on change: photograph a lesion or record unusual breathing without provoking it. Contact your vet according to the risk table, rather than waiting for an arbitrary three-week deadline.
Common mistakes to avoid
- Keeping the entire enclosure hot, with no usable cool retreat.
- Assuming a desert-associated snake never needs access to a suitable humid microclimate.
- Feeding extra meals because the snake still appears interested.
- Handling straight after a meal or repeatedly disturbing a newly arrived snake.
- Peeling retained eye caps or treating skin disease with unprescribed chemicals.
How can you prevent recurring problems?
Remove waste promptly and clean contaminated furnishings when needed. Review the setup as the snake grows, and offer safe routes, hides and textures that encourage exploration without constant rearrangement. Establish a reptile veterinary relationship before illness occurs.
Keep new arrivals separate from existing reptiles with dedicated equipment and a veterinary quarantine plan. Wash your hands after handling the snake, its enclosure or prey, and keep these tasks away from food preparation areas.
Frequently asked questions
Can a woma live with a black-headed python?
No. Use separate enclosures for pet snakes. Similar appearance or shared genus does not make cohabitation safe.
Is a black-headed python a desert snake?
Not exclusively. It occurs across several northern Australian habitats, so an extremely dry enclosure is not automatically appropriate.
How long can a woma python go without eating?
There is no single safe deadline. Age, body condition, weight trend and other symptoms matter more than the number of missed meals. Seek prompt advice for weight loss or illness signs.
Should I handle my python after feeding?
Avoid routine handling for three days after a meal. Give it access to its normal temperature gradient and secure retreats while it digests.
Can I pull off a retained eye cap?
No. Removing it incorrectly can injure the eye. Have a reptile veterinarian assess the retained shed and the conditions that contributed to it.
