Sometimes when I go to check on Kingsley he is just sitting on his log and his mouth is open. We are trying to get him used to us dripping water in his mouth. Is that a sign of being thirsty? He doesn't always take the water. We mist him frequently and gets a bath about every other day so I am pretty sure he is hydrated just fine. Does anyone else see this with their beardie?
They usually open their mouth when they need to regulate their body temperature. Think of it like a dog panting when it gets hot or us sweating. It's not a sign of being thirsty. The only other concern would be if they had a respiratory infection. You would probably see mucous coming out of the nose and/or mouth though.
Yep that's common and a sign that they are content and basking. It lets them get plenty of heat to their body while keeping their head a bit cooler. My avatar is a photo of Cooper doing the same thing =)
