I have a Haitian, and since yesterday morning, he's been sitting in one spot, with his head up, and does a "hick-up" motion. Meaning, every once and a while he opens his mouth, and almost acts like he trying to swallow something. He went in his den last night I'm assuming, but hasn't come out but he's still doing the "opening of the mouth" thing. Any suggestions? I don't think he's choking otherwise he'd be dead by now. And there are no vets around here specialized in reptiles so, any help is appreciated. Thanks.
