I use aspen bedding for all my ball pythons and I have read that it can attach to a males hemipenes in the course of breeding and cause an infection if it is drawn back inside with them. My question is to the people who use any type of chip substrate. Do you switch to paper substrate while pairing your BP or do you continue to use your normal substrate? If you continue using your normal have you ever had any problems with doing so? This is the first year that I will have more than 1 female up to breeding size and this question has been weighing on my mind as I get ready for the upcoming season.
