just a word of advice .. never EVER listen to advice or oponions given by clerks in pet stores .. you need to realise they are mostly students and similar trying to make a living .. and yet they seem to know everything about everything :O quite interesting .. if you got questions related to ball pythons this is where you ask them .. I myself started 2 years ago and it is due to ball-pythons.net and the experts willing to help out newbies like I was that I was able to take perfect care of my pythons :) - they are healthy, breeding and beautiful :) .. i read the answers to your post and as always they are spot on .. must say I love ball-pythons.net and the community here, let's keep up the good work guys! for the love of our animals and the hobby itself!
