Help my bearded dragon hasn't pooped in 2 days and he usually leves me a big poop in his tank every morning. I adopted him from his previous owner who put sand in his tank(but that was over 1 month ago) but now i have white paper in it. I feed him kale and crikets. I also took a look at his vent and there seems to be dry poop clogging it. What can i do?!?
