Day: a real gradient, 29–32°C warm against 21–24°C cool, so the animal chooses. Night: 21.1°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 ».

Common questions

Is this a good first snake?

Yes. Calm, hardy, and it takes frozen-thawed rodents reliably. One of the easier rat snakes.

Does it bite?

Rarely. Babies can be jumpy, but adults usually settle down quickly with regular handling.

How long does it live?

Twenty years or more with good care, so please treat it as a long commitment.

How much does it cost per month?

Very little. An adult eats about one rodent a week, and the electricity for heat and light costs more than the food.

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.
