Overview

What is this animal?

  • Carpet pythons are semi-arboreal Australasian pythons kept in several regional forms, with jungle and coastal carpets the most common.
  • Adults are large but slender, with striking gold-and-black patterning in good lines.
  • They make an excellent step up from a corn snake or ball python: bigger and more alert, but far more manageable than giant constrictors.
  • A snappy juvenile phase is normal and almost always settles with calm, regular handling.

Temperament

  • Expect a defensive, nippy hatchling: this is the breed-typical phase that puts beginners off and rewards patient keepers.
  • With short, consistent sessions, the large majority grow into calm, confident adults.
Show 2 more
  • Adults are alert and engaged, watching the room from their perch and exploring vigorously during handling.
  • They are strong for their weight; support the body and keep sessions unhurried.

A good fit for

  • Keepers ready to move beyond beginner snakes
  • Fans of display animals that actually use height
  • Patient handlers unbothered by a nippy juvenile
  • People comfortable with frozen-thawed rodents

Common mistakes to avoid

  • Giving up on a snappy juvenile too early
  • Loose-fitting lids: carpets find every gap
  • Overfeeding food-motivated adults into obesity
  • Underestimating a multi-decade commitment

Enclosure

Minimum 22 sq ft of floor · 6.5 x 3.3 x 6.5 ft

Must be housed alone. Solitary; house singly

  • An adult needs a secure vivarium at least as long as the snake and half as wide, and tall enough to climb: at least 6.5 x 3.3 x 6.5 ft for a typical 6.5 ft adult, and longer for a big coastal carpet.
  • That height means a room-height build, usually made to measure, and sturdy branches or shelf perches let the snake loop and survey, which is how carpets naturally rest.
  • Juveniles feel safer starting in smaller, cluttered enclosures.
Show 2 more
  • Provide a basking surface of about 91-100°F and a cool end around 75-79°F, a large water bowl, and hides at both ends.
  • Locking doors matter: carpets are strong, curious, and famous for testing enclosure seams at night.

Tools

Care in depth

Diet

Carnivore: frozen-thawed rodents
  • Feed appropriately sized frozen-thawed rodents: weekly for growing juveniles, stretching to every 10-14 days or longer for adults.
  • Carpets have strong feeding responses and take prey readily.
  • That same response causes most bites: use a hook or paper-towel tap to signal handling time rather than reaching in at feeding hours.
  • Obesity is common in adults, so resist the urge to feed an always-hungry snake.

Health

Signs of good health, and the common problems
  • Captive-bred carpets are robust; most issues are husbandry-driven: respiratory infections from cold, damp setups and scale problems from dirty substrate.
  • Quarantine new animals and source captive-bred only.
  • Maintain shed-friendly humidity spikes around shed time, and check that sheds come off complete, including eye caps and tail tip.
  • A 20-30 year lifespan makes the vet-access and estate-planning questions real ones.

Is this urgent?

5 warning signs and how fast to act, 2 of them right away

Most snake worry is about feeding, and most feeding worry is misplaced. Check the guide for this species' normal fast before treating a refusal as illness.

Go now

Open-mouth breathing, bubbles at the nostrils, or an audible whistleGo now. Respiratory infection. Most snakes have only one working lung, and even boas and pythons, whose second lung is much smaller, have little reserve.
Now
Cannot right itself, or holds the head and neck in an unnatural twist (a western hognose that rolls over and plays dead when disturbed, then recovers once left alone, is showing normal defensive behaviour)Go now. Neurological signs are always urgent in a snake.
Now

Today

Retained eyecaps after a shed, or a ring of stuck shed on the tail tipRaise humidity and provide a damp hide. Call if it is not resolved within a day. Almost always humidity that was too low during the blue phase. A constricting ring costs the tail tip.
Today

Soon

A regurgitated mealDo not offer food again for at least a fortnight. Check the warm-end temperature today, then call if it happens twice. Usually too cold, handled too soon, or a meal too large. Repeated regurgitation is a different and more serious problem.
Check today
Refusing food for longer than is normal for this speciesLog the refusal and check the species guide. For an adult ball python, a fast of about a month is not in itself a cause for concern, and much longer voluntary fasts are documented. Weigh weekly through it. The weight trend, not the calendar, is what tells you whether a fast matters.
Log it first

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it, and the time to find one is before you need one.

Bedding and substrate

5 safe, 1 with a caveat, 2 to avoid

For snakes the substrate has to hold the right humidity for the shed, and let the animal get fully under it.

Safe

Cypress mulchHolds humidity without going sour quickly. A common default for tropical snakes.
safe
Aspen shavingsThe classic for colubrids. Excellent for burrowing; replace any patch that gets wet.
safe
Topsoil and coco fibre mixBioactive-ready and holds a burrow.
safe
Sand-topsoil mixFor arid and sandy-soil burrowers such as hognoses: plain topsoil with some play sand mixed in holds a burrow. Keep it dry.
safe
Paper towel or newspaperQuarantine, feeding response problems, and post-surgery.
safe

With a caveat

Aspen in a high-humidity setupIt moulds. Aspen suits dry-side species; wet species need mulch or soil.
with a caveat

Never

Pine and cedarThe same aromatic oils that make them unsafe in small-mammal bedding.
never
Pure loose sand for species from humid habitatsIt holds little moisture, which makes shed problems more likely, and it does not hold a burrow. A soil mix with some sand is fine for snakes from sandy, dry habitats such as hognoses and sand and rosy boas.
never

Stuck shed and retained eyecaps are usually a humidity failure during the blue phase, not a substrate failure afterwards.

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

Minimum 22 sq ft of floor · 6.5 x 3.3 x 6.5 ft

Every figure, and where it comes from

Sized for a typical 6.5 ft adult, with its full length in height to climb. A carpet python longer than 6.5 ft needs an enclosure at least as long as itself and half as wide; Swiss law also asks three quarters of its length in height, which the 6.5 ft here covers up to about 8.5 ft.

Minimum floor area22 sq ft of continuous, unbroken floor
As dimensions6.5 x 3.3 x 6.5 ft
Height6.5 ft minimum. This species climbs, so height is not optional.
CompanyMust be housed alone. Solitary; house singly
The recognised standards do not agree on this one
RSPCA Australia: 6.5 ft long, 39 in wide and 6.5 ft high for an adult of 3.3-6.6 ft. The figure this site uses. The RSPCA adds that the larger the snake, the larger its enclosure should be, with room to climb as well as to move on the ground. Checked 2026-10-23.
German expert report on minimum requirements for keeping reptiles (BMEL, 1997): Three quarters of the snake's length by half its length by its full length for one under 6.5 ft, about 5 x 3.3 x 6.5 ft for one just under 6.5 ft, with height capped at 6.5 ft. A minimum standard, recorded for context. It backs the full 6.5 ft of height used here. Checked 2026-10-23.
ReptiFiles: 6.5 x 3 x 3 ft minimum for a 6.5 ft adult, the snake's full length by half its length and at least 35 in high; its recommended enclosures run from 7 x 3 x 3 ft to 8 x 4 x 4 ft. ReptiFiles strongly recommends going larger than its minimum, particularly taller. Checked 2026-10-23.
Swiss legal minimum (Tierschutzverordnung, Anhang 2, Tabelle 5, row 43a, which names Morelia spilota): As long as the snake, half its length wide and three quarters of its length high, for one or two: 6.5 x 3.3 x 5 ft for a 6.5 ft snake. A legal minimum, recorded for context. The figure used here meets it for a carpet python of up to 6.5 ft in length. Checked 2026-10-23.
Austrian legal minimum (2. Tierhaltungsverordnung, Anlage 3): 16 sq ft of floor and 59 in of height for one or two adults (Morelia spilota). A legal minimum, recorded for context. Less than the figure used here. Checked 2026-10-23.

What it really costs

Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.

Everyday foods (1)

Frozen-thawed rodentsThe whole diet for these snakes. Choose prey no wider than the snake at its thickest point. Thaw fully in the fridge, then warm in a sealed bag to about 100°F and offer with tongs. One prey item per feed, at the interval in the species guide.
everyday food

That food is not on our list. A snake eats whole prey and nothing else, so if it is not a correctly sized prey item from the species guide, leave it out.

Whole prey is a complete food: snakes fed whole rodents need no supplement dusting.
