Olive python

Resolve the form before preparing the adult home

Keep the scientific name and origin records with the animal. This guide covers the nominate olive python, Liasis olivaceus olivaceus. A Pilbara animal, L. o. barroni, needs a separate complete care plan; a similar colour does not establish identity. Plan for a snake several metres long and confirm your veterinary transport and backup carers before acquiring a juvenile. The zoo's approximate ≈ 137.795″ (3.5 m) adult figure is a planning reference, not a maximum. House one animal.

Our recommended adult enclosure

For one nominate adult up to ≈ 137.795″ (3.5 m) total length, we recommend ≈ 141.8″ × 59.1″ × 63″ (3.6 × 1.5 × 1.6 m), usable internal length × depth × height. Height includes a ≈ 3.937″ (10 cm) substrate allowance, leaving ≈ 59.055″ (1.5 m) above it before fixtures. This is our editorial welfare minimum. It provides complete straightening, turning space and low climbing, using the general spatial framework rather than treating a historical breeder cage as an adequate lifelong limit.

Keep length at least equal to the snake's measured total length, including its tail; keep depth and clear movement height at least 40% of that length. Retain the base envelope and add the substrate layer. For a measured ≈ 157.48″ (4 m) adult, that gives at least ≈ 157.5″ × 63″ × 67″ (4 × 1.6 × 1.7 m). No separate preferred triplet is established: extra usable floor is worthwhile when large hides, water and branches occupy the minimum. Juvenile accommodation is temporary. Measure the furnished interior; dimensions alone cannot establish suitability.

Make movement and servicing work together

Keep a dry full-length route between warm and cool cover. Install secure low branches or platforms, with supports anchored independently of loose bedding. One breeder saw little branch use, while another observed regular climbing; retaining usable choices accommodates that variation. Make every hide inspectable without pulling the animal through a narrow log.

Our ≈ 3.937″ (10 cm) substrate allowance supports a cleanable soil or bark layout with a dry surface; it is not a proven digging requirement. Removable paper is useful during arrival monitoring. Keep fresh water continuously available in a stable vessel allowing voluntary full-body soaking. A keeper's failure to observe soaking does not establish that water access can be reduced. Trial basin cleaning and waste removal with the facility empty, using protected service access and secure temporary containment.

Measure local warmth and the night refuge

Use a basking area near 95 °F (35 °C) and a cool retreat around 77 °F (25 °C), following the species veterinary protocol. Because its basking measurement is not fully specified, check the contact surface and adjacent air separately. Use independent probes at occupied retreats, a surface thermometer, a thermostat and protected heaters. Keep warm-end air from remaining below 68 °F (20 °C) at night. This is a practical veterinary operating reference, not a proven physiological boundary. Preserve a cooler choice and avoid heating the whole enclosure to the basking value.

Where seasonal recommendations differ

Historical breeding accounts report much colder winter conditions, including room lows around 63 °F (17 °C) and colder substrate, while other keepers change warmth around reproduction. Those accounts describe complete seasonal facilities and sometimes identify health risks. We choose the veterinary routine above for ordinary non-breeding care. Reproductive cooling needs a separate reviewed programme; selecting a cold extreme from one report and a hot extreme from another does not create a sound routine.

For moisture, use 50–60% at a shaded occupied position as a provisional species retail reference, with dry exposed resting surfaces, ventilation and a localized humid retreat. Breeder descriptions of dry housing do not report a matching measured percentage. Judge the water supply, hidden dampness and shed quality together with the meter; do not saturate the entire enclosure to meet one reading. This recommendation is practical guidance, with limited comparative evidence.

Keep light and heat independently controllable

Provide about 12 hours of daylight and a dark night for ordinary care. The veterinary sheet describes shorter winter days, but seasonal changes should be part of a coherent plan. We recommend voluntary daytime UVB access with complete shade. The reviewed sources do not establish a measured olive-python UVI (ultraviolet index) target or prove that every animal requires the same exposure. Commission the dose for the installed lamp, distances and barriers with qualified review before use. A lamp percentage and a calendar replacement rule cannot establish the exposure reaching the snake.

Feed for steady condition

Use appropriately sized, completely thawed whole prey from a dependable supplier. Begin established youngsters around every 7–10 days and mature adults around every 2–3 weeks, then adjust portions and interval to growth and body condition. The first interval follows species keeper practice; the adult interval follows veterinary guidance. Adults receiving larger meals may need longer intervals. Seasonal feeding surges in breeding females are not our default for a non-reproductive pet.

Record meals and comparable weights, and reduce intake if condition becomes excessive. Keep meal presentation distinct from maintenance and arrange competent help for adult transfers. Some youngsters require particular prey types, so obtain repeated voluntary feeding records before purchase. A balanced whole-rodent diet generally needs no routine vitamin powder; a different diet or medical problem needs its own nutritional assessment.

Maintain a care routine another keeper can use

Check locks, water, occupied temperatures and visible condition daily. Remove waste promptly and inspect moisture under large furniture. Arrange separate arrival care with a reptile veterinarian and keep the feeding and shedding history transferable. Abnormal breathing, repeated regurgitation, poor sheds, injury or sustained loss of condition require assessment; a report of seasonal fasting does not rule out illness.

Write down safe water-changing, containment and transport procedures for the actual adult facility. Arrange experienced assistance rather than relying on a reputation for docility. Confirm that the receiving veterinary practice can accommodate the animal and that the route out of the building works. Precise species longevity is uncertain in the zoo account, so plan for a long responsibility and changes in your own circumstances.
