🏠 Enclosure

For a modest adult, start around 120 x 60 x 90 cm; active animals benefit from larger and taller housing. Juveniles can start smaller, but still need secure hides, water, climbing structure, and a real thermal gradient. Adults need stronger locks and more usable space.

🪨 Substrate and furnishings

The enclosure should be functional first: secure hides, climbing or burrowing structure, anchor points, water, and enough cover to make the animal feel hidden.

Use decoration as working habitat rather than ornament. Substrate depth, cork tubes, bark slabs, branches, plants, leaf litter, and visual barriers should create routes and retreats. Leave enough open access for cleaning and observation, but do not make the animal choose between being visible and feeling secure.

💡 Lighting

Use a regular 10-12 hour day-night cycle with bright visible light. Low-level UVB is recommended as an option, especially over part of the warm side, but the python must have shaded retreats and routes away from UV exposure.

🌡️ Temperature

Practical temperature targets: basking surface 31-33 °C, warm side 27-29 °C, cool side 23-25 °C, night 21-23 °C. Measure with reliable instruments. Stable warmth is useful, but overheating and stagnant hot air are more dangerous than a mild night drop.

Seasonal changes should be gentle. Small shifts in appetite, activity, or hiding can be normal, but large swings in temperature or moisture are not a substitute for stable husbandry. Change one variable at a time, wait long enough to see the result, and avoid correcting every minor behavior with extra heat, extra spraying, or repeated feeding attempts.

💧 Humidity and water

Humidity and water target: 50-70%, with a humid hide or slightly higher moisture during shed. Fresh water should always be available. Moisture should be balanced with ventilation; wet, stale air is not good humidity.

🪳 Feeding

Suitable diet: appropriately sized frozen-thawed mice, rats, or chicks, adjusted to age and body condition. Remove uneaten prey and food remains. Feed according to body condition, not only appetite, and avoid leaving live prey unattended.

Feeding should follow natural ecology but stay practical and hygienic. In nature, it is an active nocturnal python that uses both branches and the ground, with a strong feeding response and clear preference for secure elevated routes. In captivity the core plan is frozen-thawed rodents or occasional chicks sized to body condition, with care not to overfeed juveniles that strike readily. Keep a log of prey type, prey mass, date, shed stage, defecation, body weight, and refusal. That record prevents overreacting to one missed meal and exposes slow obesity before it becomes normal. Avoid live prey as routine care because bites and stress are preventable. If a reliable feeder suddenly refuses, review temperature, privacy, seasonal timing, recent handling, prey size, and illness signs before trying repeated meals.

☠️ Safety

Handling should be calm, supported, and planned. Jungle carpet pythons can move quickly and may strike from food expectation, so use hooks or shift routines when opening the enclosure, wash hands before handling, and keep sessions short. Children should not handle this species unsupervised.

🩺 Health — warning signs

Common problems: retained shed, defensive feeding responses, nose rubbing, respiratory infection, burns, mites, obesity, and injuries from weak branches or escapes. If problems appear, first verify temperature, humidity, water, ventilation, prey size, hide fit, and recent disturbance. Serious injury, bleeding, repeated regurgitation, breathing signs, or a difficult shed need experienced exotic-veterinary help where possible.

Keep a simple written baseline for the first months: normal posture, preferred hide, drinking, defecation, feeding response, and reaction during maintenance. That baseline makes it easier to tell normal fasting or hiding from weight loss, dehydration, respiratory trouble, shed trouble, or pain.
