Part of the Pythons
Pythons are non-venomous constrictors of the Old World tropics and subtropics, ranging from small, beginner-friendly species to giants. Many are hardy, long-lived, and popular in the pet trade, though the largest species carry serious legal and safety considerations.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Adult arboreal enclosure
6 × 2 × 3 ft (≈ 140 gal)
Carpet pythons (Morelia spilota) reach 6–8 ft and are highly arboreal. Minimum is a 6×2 floor with 3 ft of height, sturdy branches, basking 32 °C, cool 24 °C, humidity 60–70%.

Recommended
Tall front-opening vivarium
6 × 2 × 4 ft with branches
A 6×2×4 with extensive climbing structure (varied diameters), multiple elevated hides, and a basking branch. Carpet pythons use vertical space heavily.

Ideal
Bioactive arboreal enclosure
8 × 2 × 4 ft, bioactive
Large bioactive Australian forest enclosure with deep substrate, dense vertical climbing structure, and live plants. Best welfare for this active intelligent species.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg / Neonate
Most reptiles lay leathery- or hard-shelled eggs incubated by ambient warmth, though some snakes and lizards give live birth. Incubation temperature can influence sex and development in many species.

Hatchling
Hatchlings emerge as fully formed miniatures of the adult, often using an egg tooth to slit the shell. They are independent from birth but small and vulnerable, and may show brighter or different juvenile patterning.

Juvenile
Juveniles grow steadily, shedding their skin periodically as they enlarge. Coloration and proportions shift toward the adult form, and growth rate depends heavily on temperature, diet, and basking/UVB access.
Adult
Adults reach the species' full length and mass and become sexually mature. Many reptiles show sex differences in size, coloration, or features (such as larger heads, hemipenal bulges, or femoral pores), and continue to shed throughout life.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Carpet pythons are strong climbers, so they need both floor space and height. An adult should have an enclosure of at least 6 x 2 x 2 ft, with the taller subspecies appreciating 3 ft or more of height. Outfit the cage with sturdy horizontal climbing branches, elevated hides or shelves, ground hides, a large water bowl, and a substrate such as cypress mulch, aspen, or coconut fiber. A secure, lockable enclosure is essential for these powerful, inquisitive snakes.
Provide a basking spot of 88-92 F (31-33 C), an ambient warm side of 82-85 F (28-29 C), and a cool side around 78 F (26 C), with a modest nighttime drop. Humidity of 50-60% works well, raised during sheds. Use thermostat-controlled radiant heat panels or basking bulbs; UVB is beneficial but optional for this nocturnal-to-crepuscular species.
Substrate
Cypress mulch or coconut husk works well to balance moderate humidity, or aspen for a drier setup; provide several inches so the snake can move comfortably. Spot-clean regularly and avoid cedar/pine.
Equipment & setup
These semi-arboreal pythons need a tall enclosure with a basking spot of 88-90F, ambient mid-70s to low-80sF, and a cooler night drop, all run on thermostats. Provide sturdy elevated branches and perches, moderate humidity around 50-60% (higher during shed), a large water bowl, and elevated hides; UVB is optional but beneficial.
Diet
Carpet pythons eat appropriately sized frozen-thawed rodents, progressing from mice and rat pups as juveniles to adult rats for grown adults; large coastal individuals may take small rabbits. Feed juveniles every 5-7 days and adults every 10-21 days, sizing prey to the snake's girth and adjusting for body condition.
They have a notably enthusiastic feeding response, so use long tongs and a deliberate approach. Avoid overfeeding, as obesity is a common captive issue in this species that readily takes meals.
Behavior & temperament
Hatchling carpet pythons are often defensive and nippy, but with consistent, gentle handling most calm considerably as they mature into alert, manageable adults. They are active and arboreal, frequently using branches and elevated perches, so a tall, well-furnished enclosure supports natural behavior.
Handle regularly but read the snake's body language, and always use tongs at feeding time given the strong food drive. Enrichment through climbing structures, varied perches, and occasional rearrangement keeps these intelligent, exploratory snakes engaged.
Health
Respiratory infections can develop if enclosures run too cool or humidity is poorly managed; watch for wheezing or open-mouth breathing. Stuck sheds and retained eye caps occur with low humidity, corrected by raising humidity during shed cycles and providing a humid hide.
Obesity from overfeeding, scale rot from damp dirty substrate, mouth rot, and mites are all possible. Thermal burns from unguarded heat sources are a risk for climbing snakes, so guard all heat elements. Given their long lifespan, establish care with an experienced reptile veterinarian and quarantine new animals.
Tips, DIY & hacks
Give strong climbing branches at multiple heights since they spend much time elevated and use perches for ambush enrichment. Be aware juveniles are nippy and have a strong feeding response, so use a hook to signal handling vs. feeding. A radiant heat panel mounted overhead suits their arboreal basking better than a UTH alone.
