The signs are typically reduced appetite, lethargy, and the big one is very stinky poo. Sometimes they are okay except for the poo smelling. Depends where you get a fecal done - at a vet, probably $30-50 at a vet. You can also get one done by Cheryl and beardeddragon.co. They are much cheaper - I want to say $5-7, but don't quote me on that! You would just have to send it to her in the mail following her directions.
