I don't know but it only costs about $15.00 to take the pooh to the vet (cham stay home) and they can do a fecal on it, our cham seems normal, content, and healthy, and I took his this morning just to get it checked and found out he has pin worms and COCCIDIA!!!!!! Which can be lethal if left untreated under certain varying circumstances, so even if all seems fine, have it checked yearly (the poo)
