Clear wet discharge

[Minimum3]

Phira has been going poo on his normal schedule, but I've noticed that there is a watery clear discharge when he poos. The poo would be solid and healthy if not for this. Is it urine that is not getting put in the little white pouch thing? My Lizard Vet is some 80 miles away and Phira does not like LONG car rides. Does anyone know what this watery discharge is before I stress him out and pay a very large Gasoline bill? (Not that he isn't worth it)

The poo will often come out with a bit of water, that's normal. If you want, post a pic here.
