All bark? (hissing BP--and need some cleaning/handling advice)

My boa hisses are also much more intimidating. Fortunately they are very, very rare!

Very true. I don't hear them all too often, but boy can those guys hiss!!! The first time I ever heard my BCI hiss, she was tiny still, and it sounded like it belonged to a MUCH larger animal.
