They do love to poo on you :p
Also look up the bite reports and understand what "hair kicking" can do to you. Don't trust the people at the pet store for care info. Personally I would stay away from wild caught.
Bobbafett,
How much are you feeding that Chilean Rose? Looks to be on the skinny side.
I took about 12 years before my rosea threw up a threat pose, so never let your guard down :p
