Sorry to start it off with that strange image, but my bearded dragon's poop nearly never looked like this, and he refused to eat for 2 days before it. After, he seemed to accept some dubia roaches. He is a juvenile beardie, around 4 months. His temperature gradients are correct, he has a 10% uvb lamp, all of the things you'd normally expect an enclosure to have.
Is this vet-worthy? Any ideas what would make his poop look like this?
