Then it is time for a fecal. Arcadia supplements have no risk of toxicity even when used incorrectly and you are using them perfectly.Everything else is normal he’s just not eating and I use the Earth A supplements daily and the Arcadia D3 every other Monday
Call around and see if they can just take in a fresh fecal to drop off. Let the Vet know you are out of town currently and are happy to bring him in if the fecal comes back positive but you want to limit stress since your not there to bring him in right now. Make sure they are an exotic vet and or have a vet on staff that works with chameleons.
