I have two sulcatas, they live outside and have a burrow and it gets really hot here about 110° mid day so sometimes I’ll put some water into the burrow for them. Just enough to wet the dirt to keep the temp down since the burrow is man made and only about two feet down. We have a mound of dirt about 3 feet on top of the burrow to help keep it cool for them but I started noticing my bigger sulcata whistling out of her nose. I thought maybe it’s because it’s too wet down there so I’ve recently stopped wetting it. I researched and found this could be the beginning of a respiratory infection. She still eats a lot and is very active. What steps can I take to prevent it from developing any further and possibly curing it in its current stage.
