Ball Python (Royal Python)

Python regius

Updated: September 2025

Quick Facts

COMMON NAME: Ball Python (Royal Python)

SCIENTIFIC: Python regius

TYPE: Terrestrial/crepuscular; benefits from climbing opportunities

ADULT SIZE: ~3–5 ft typical (up to ~150 cm)

LIFESPAN: 20+ years in captivity

TEMPERAMENT: Shy; prefers multiple secure hides

ADULT ENCLOSURE: 48×24×24" (4×2×2 ft) or larger; ideally at least the snake’s full length

SUBSTRATE: Moisture-retentive options like cypress mulch or coco husk/chips. Avoid cedar/pine/aspen.

TEMPERATURE: Basking surface 95–104 °F; warm hide 86–90 °F; cool hide 72–80 °F; night 70–78 °F (air temp should not exceed 95 °F)

HUMIDITY: ~50–60% and ~80% for shed

WATER: Heavy bowl large enough for full soak; change daily

FEEDING: Juveniles ~weekly; adults every 10–14 days (adjust to body condition)

HOUSING: Keep singly (no cohabitation)

  • Size — Adults over ~3 ft do best in 48×24×24" (4×2×2) or larger. As a rule, house them in an enclosure at least as long as the snake so it can fully stretch. Provide some vertical space for climbing.

    Layout — Secure ventilation and a tight front-opening door/lid. Add multiple hides (warm end + cool end) and sturdy cover/branches so the snake feels secure.

    Substrate — Cypress mulch, coco chips/husk, or similar hold humidity well. Do not use cedar, aspen or pine.

    Cleaning — Spot clean as needed; periodic full cleans with reptile-safe disinfectant.

  • Temperatures:

    • Basking surface: 95–104 °F

    • Warm hide (ambient): 86–90 °F

    • Cool hide (ambient): 72–80 °F

    • Night: 70–78 °F

    • Keep general air temps under 95 °F. Use thermostats and measure with digital probes + an IR temp gun for the basking surface.

    Humidity:

    •~50–60% with temporary boosts to ~80% for shedding

  • Day/night cycle ~12 hrs. Low-level UVB is recommended (e.g., T5 HO 5%/Arcadia 6%) with shaded retreats; follow lamp distance guidance and replace bulbs per instructions.

  • Prey — Thawed/warmed rodents (about the snake’s widest-girth size).

    Frequency — Hatchlings every 5-7 days. Juveniles roughly weekly; adults about every 10–14 days. Adjust to body condition, not just the calendar. Minimize handling around meals; avoid handling for ~48 hrs after feeding to prevent regurgitation.

  • Provide a heavy bowl large enough for full submersion at the cool end; change daily and whenever soiled.

  • Generally shy; move slowly and support the body with two hands. Provide multiple hides so the snake can choose both temperature and security. Avoid handling during shed and for ~48 hrs post-meal.

  • Respiratory signs — Wheezing/clicks, open-mouth breathing, bubbles, lethargy, appetite loss.

    Shed issues — Retained eye caps or patchy sheds (check humidity & hydration).

    Mites — Black specks that move; prolonged soaking.

    Burns — Guard all heat sources and run thermostats.

    Seek an exotics vet promptly for any of the above.

  • • Hygiene — All reptiles can carry Salmonella. Wash hands after handling the snake, enclosure items, or feeders. Keep reptiles out of kitchens/food-prep areas; supervise children and high-risk people.

    • Heating safety — Put every heat source on a thermostat and use guards around bulbs/emitters to prevent burns. Use digital thermometers to verify the warm and cool ends.

    • Housing — Keep singly (no cohabitation). Provide secure lids/locks to prevent escapes.

    • Substrate cautions — Do NOT use cedar or pine shavings (aromatic oils can harm reptiles).

    • UV & lights — Provide a 12-hr day/night cycle. If you use UVB, keep intensity low and always offer shaded retreats; follow lamp distance guidelines.

    • Local laws — Ownership/sales rules vary by city/county/state.

  • Enclosure

    • Adult minimum 48×24×24" (4×2×2 ft) with good ventilation and secure doors/lid.

    Temperature & Humidity Control

    • Primary heat: ceramic heat emitter or radiant heat panel (with bulb/element guard).

    • Thermostats: one per heat source (on/off or proportional), probe secured.

    • 2 digital thermometers (warm end + cool end) and an IR temp gun for surface checks.

    • Digital hygrometer; humid hide or moss box if needed.

    Lighting

    • 12-hr light cycle. Optional low-output UVB strip (e.g., 5–6% T5) mounted to achieve a low UVI with shaded retreats available; timer.

    Furnishings

    • 2+ snug hides (warm end and cool end).

    • Sturdy branches/plants and cover (“clutter”) for security and exercise.

    • Heavy water bowl large enough for full submersion.

    Substrate

    • Cypress mulch or coco chips/husk, (avoid cedar/pine).

    Feeding & Care

    • Feeding tongs; frozen/thawed rodents; paper towels for spot cleaning.

    • Reptile-safe disinfectant; spare bulbs/fuses; enclosure locks/clips.
