I recently purchased an adult bearded dragon. He is active and eating very well, but he has slightly runny stool. He eats a diet of mashed carrots, celery, bell peppers, some romaine lettuce, some cucumber, and crickets. I feed the crickets a high-calcium cricket diet (Total Bites). They are always gut-loaded. He is still very active and when I took him out today he ran around a lot and snuggled with me. He is not showing any irritation or anger towards me, like if he was sick. I have him in a 40 gallon tank with about a 98 degree temperature on the basking side and a 82 degree temp on the cool side. He is not sad and his eyes are not droopy. He has had kind of runny stool for about 2 days now. Is he sick with something I don't know of? Or is it just stress or diet?
