Hello! I am a new bearded dragon owner. I have a bd named Charles who I think is an adult (he's 17 inches) and for some reason he only poops outside. He pooped in his cage when I first got him but now it seems he only poops outside. I feed him dandelion greens, carrots, and prickly pear along with crickets and occasionally super worms and he eats pellet food occasionally as well. The air temp on his hot side is usually around 85-90 degrees but if I put it on his basking spot it goes up to 100. I have a reptisun 10.10 uvb currently on top of his cage bc I can't figure out how to mount it in the cage. He also has an under the tank heater and a 100w and 120v basking bulb also sitting on top of his cage. His stool seems healthy (I have a picture just in case) so I think it's the heating and lighting causing it but the temps seem right. I'm not sure. He has no problem pooping outside when it's warm out but I worry about what I'd do in the winter. If anyone could help me figure this out help would be appreciated
