Thank you both! She's doing great. I am so pleased; being my first Boa and all.
Between all the research, this forum and help from some great Boa peeps, and a tiny bit of trial and error in husbandry (getting to know her preferences in temp - she prefers it a little cooler on the hot side), I find Boas aren't too difficult at all. I had been afraid for a long time. I have to say, the upgrade in setup/tanks to Boaphiles and to top of the line heating elements and thermostats made a huge difference as well. Makes it much easier to maintain temps and humidity. Also, all my tanks being the same design and same heating elements (although a few different sizes), with the same thermostats, has made it pretty easy to fine tune for each individual animal.
Bottom line is, I am relieved and happy she's doing so well. I am also amazed that a snake as young as her can eat every three weeks now, look as good as she does, and be as healthy as she is! Boas are pretty cool in that regard.
Also, I cannot ignore her personality. She's awesome.
Thanks again.
