I have a female spider ball who doesn't poop as often as my other 3 ball pythons do. My other 3 usually go once per week but my spider only goes once per month. But now its been 5 weeks and I am beginning to worry.

All four ball pythons are kept in the same rack system which was purchased form reptilebasics.com. I use a bah-1000sc for heat control keeping the back of the tubs at 89-90 degrees.

Any advice?
