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 ».

What your climate adds

This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.

Diet

Feeding rhythm

every 5–7 dAs an adult
5Meals 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 statesWild milksnakes are known to eat other snakes, small mammals, lizards, birds, and eggs. The size of your milksnake's prey should be no more than 1.5x the width of the snake at its widest point. Hatchlings - every 5-7 days / Juveniles - every 7-10 days / Adults - every 10-14 days

Common questions

Will the colours stay this bright?

The red usually stays strong, though the bands often broaden a little with age. A good shed always brings the colour back up.

Does it bite?

Very rarely. This is one of the most even-tempered milk snakes, though it can be quick around food.

Can I keep a pair together?

No, house them separately. They can eat other snakes and there is no benefit to keeping them together.

How long do they live?

Commonly fifteen to twenty years with good care, so it is a long-term pet.

Not stated: The heat sourcethis sheet names only the cool side: « cool 23-27 °C / night 21-23 °C »

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

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.
