A Jungle Carpet Python is not a Ball Python. They are two different species with different husbandry requirements. Now, if you are sure you are speaking of a ball python morph, I agree with Mike as I would be interested to see what someone is calling a "Jungle Carpet" morph.

That being said, a JCP cannot be housed with a BP, and the general consensus for ball pythons is 1 per enclosure. There are a lot of risks housing BP's together. If one gets sick, they both get sick. If you see a regurgitated rat, you have no idea which snake regurged. etc etc. (Serpent Merchant has a nice, saved reply for this I believe, that goes into further detail)
