Drag the sun. The sheet states a night temperature, so the rail follows it.

CITES I is a global listing and holds in every country. National law is not global, and we hold no national wildlife law for any country, Thailand included. Check your own authority before buying or selling.

Day: a real gradient, 30–31°C warm against 21–24°C cool, so the animal chooses. Night: 21–24°C.

Why

Same scale on every sheet here, so two species compare by eye.

Drawn from the stated numbers. Only what the sheet states is drawn inside.

Why

The rectangle carries the exact width-to-height ratio of the figures above it, and the ruler under it places that width on the 0–250 cm scale every sheet here shares, so two species still compare at a glance. Nothing is added that the sheet does not name: a lamp drawn on a sheet that never mentions one would be invented equipment. What the sheet leaves out is listed rather than left blank, because an empty tank reads as « none needed ».

Diet

Feeding rhythm

every 21–28 dAs an adult
1Meals in 28 days

Twenty-eight days, one row. Each band is a meal window. The sheet gives several ages on one line; this is the adult figure.

Why

The windows widen as they go because the interval is a range: four meals after a 10–14 day cycle land anywhere between day 40 and day 56.

The sheet statesMice, Rats, Hamsters, Gerbils, Guinea pigs, Young rabbits, Chicks, Quail; Hatchlings and juveniles (no longer than 3′): Every 7-10 days; Subadults (longer than 3′): Every 14-20 days; Adults (no longer growing): Every 21-28 days

Common questions

What is its temperament like?

One of the calmest boas we keep. Most are slow, steady and very tolerant of handling once they are settled.

How big does it get?

Usually around two metres but very heavy-bodied, so plan for a wide enclosure with plenty of floor space.

Does it climb?

Not much, it is a ground snake. Floor area, hides at both ends and a large water bowl matter more than height.

Are there any import restrictions I should know about?

This species is regulated internationally, so always buy with the correct paperwork and keep your documents. Ask us and we will show you ours.

What this sheet states

TemperatureHumidityEnclosure sizeActivityOriginDietSourcesUVB

This sheet states 5 of 7 of the fields this product runs on. What is missing turns something off: day/night engine and awake count on the globe, the diet section. We show the gap rather than fill it with a plausible number.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
