the Caulker Cays are great boas. as with most boas, they should be of three years of age or older before you attempt breeding.

I would also go with lower temperatures than the 80 cool 90 warm. I keep my girl at 85-88 hot end and 75-78 cool, but generally it stays in the 85 range.

This is my Female, Sha're, she has bitten me only once, during feeding time, and it was my own fault. She hasnt offered to bite me any other time since after the first week i got her, ( acclimation and such, all the stress can make them more nippy, as would young age)
But shes an absolute doll now.
