I have learned with any snake... I tilt them over a paper towel first and do a few thumb rolls... as inevitably they are going to urinate of defecate...
I was in a pet store and the woman asked me to sex a shipment of baby BPs, being the fool that I am I agreed... first one projectile peed in my eye and blinded me.
Since then I am a bit more cautious, but I still do it.
