Common questions

Why is this boa so much more expensive than a normal one?

It is a protected species with restricted trade, so legal captive-bred animals with paperwork are limited in number and priced accordingly.

Is it as calm as a common boa?

Often a bit more defensive, especially when young. Many settle well with consistent handling, but do not assume it will be as easy-going.

How big does it get?

A large heavy boa, commonly around two and a half metres, so it needs a big adult enclosure and two hands to handle.

Do I get documents with it?

Yes, and you should never buy this species without them. Keep the paperwork with the animal for its whole life.

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.

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.
