For the last 3 weeks or so, my leo has been refusing most food (will not touch mealworms, will take waxworms occasionally). I have been feeding him Carnivore Care during this time. He just shed yesterday, and with the exception of one hind foot, he shed completely and ate it all. I normally don't see him drink, but I have watched him drinking continuously from his bowl for the last 25 minutes. He wont stop. Are these occurrences put together a cause for concern?
