This is my first year owning a bearded dragon and my first winter with him. Recently he's started going into his cave all day instead of being out and basking like he usually is. I figured he was probably brumating. But instead of sleeping, which I think is what they usually do during brumation, he's just sitting in there awake and alert, I'm not sure if thats normal. He doesn't become aggressive when I take him out of his cave and he eat all his veggies and eats his live meals normally, but sometimes he won't eat any live meals the entire day, only his veggies. He's not pooping as much as he was before he started this strange behavior. I have him in a 40 gallon tank, with a 100watt basking bulb on the rightside as well his uvb bulb. The left side of the tank is the cool side. The basking bulb is over his basking rock which is also his cave. Any thoughts on if this behavior is normal? Should I take him to a vet or maybe lower the temperature in his tank? Usually I take him and put him on his rock to bask but after maybe 30 minutes he'll go back into his cave. Thank you
