My new Spider Ball Python (Peter Parker is his name) Keeps pooping on me! I have had him for 2 weeks and have held him like 3 times, and 2 of those times he pooped. Does this normally happen more often with spiders?

He has already had his first meal with me... no problems there. He was hatched in August of 07. His stool is pretty runny. Could this be and indication of parasites or something??? Could it just be that he is not used to being handled, and in time this will stop??

I have certainly been pooped on over the years... but this guy seems to do it every time I pick him up! My wife wants to rename him to "peter pooper"
