snake cough

[Salamander Rising]

Has anyone had a snake cough? The other night my female pastel ( six months old ) was sitting in her tank and she opened her mouth wide open and let out what sounded like a cough or a retching sound. She did this 3 times then sat for a second with her mouth open and then went back in her hide. It had been three days since she ate. The temps and humidty were all spot on and she has no audible breathing issues. I would appreciate any feedback. I have never had this happen before and thought it was strange. Thanks

How long has it been since she ate?

I just read an old thread on here last night where somebody's BP did that and they'd possibly eaten their food backwards and the fur or a claw irritated their throat.

Here's hoping it was nothing more than just one of their usual "scares us half to death" but-means-nothing incidents.
