My bearded dragon Zeus has had some watery eyes to the point of a "tear" falling every once in a while. I notice this around feeding time more often, so could it be the smell of his food? On top of his veggies and roaches, he gets Flukers Buffet Pellets and T-Rex's Gourmet Blend mix. He really likes those and go for them more than eating his veggies, so Im rather hesitant to stop giving those to him. The gourmet blend has a strong smell though and you can smell it when you walk into the room. Could this be whats bothering him? I dont see anything in his eyes and he seems perfectly normal in every other way.
