My Sulcata all of a sudden cut loose with a massive amount of dark brown urine (diarrhea?) with brown solids in it and is foaming at the mouth. I am in the waiting room at the vet in a total panic. Has anyone experienced this before? He is a rescue I have had for 2 Yrs so I have no idea how old he is. he weighs 13 lbs and came to me with a terrible shell and could not support his own weight. I'll attach some pics.
