My BP whistles

[Denial]

Well I had my vet appointment today.
I was surprised that he was hesitant to pick the snake up from its container. he asked me to do it since the snake wasn't used to him. Is this unusual? Again it was my first reptilian vet appointment.
He said the whistle was actually a hiss. I think if its a hiss its a rhythmic hiss that mimics a breathing pattern, but he's the doc, right?
He did check out his mouth (wow, pretty nasty-sharp set of teeth in there) and said no RI.
There are some retained eye caps but he said give it two weeks to come off on their own, otherwise he will remove them.
So I've bumped the humidity up to 75-80%

sounds like you need to find a new herp vet. Also whistling sounds came be a number of things. Doesent automatically mean its a r.i.
