So my bearded dragon Spike is exhibiting some behaviour that has me a little concerned. Today he was making a TON of noise downstairs, every time I went to check on him he was running around, trying to climb the glass walls, and even banged his head on the walls a few time. He seems to have calmed down now but I'm a little concerned. It was almost like he couldn't sit still, he just kept running from one end of the cage to the other. Has anyone else seen their dragon do this and what does it mean?
