Hi everyone! I have a cornsnake (she is about 6 years old) who is sick. She has been sitting with her mouth open very often over the past few days. She also looked like she was having some difficulty breathing. We took her to our vet, got x-rays, etc. and there is apparently nothing wrong with her lungs. She is not foaming or bubbling around her mouth or nostrils and her lungs are full of air. She was put on antibiotics, which she has now been on for 4 days. We have been noticing that she is very lethargic, and at times, looks like she is seizing (weird, erratic head movements, rubbing her head on her body or on the tank, etc.). Then she just goes back to being normal. (Right now she is soaking in her water bowl.) She almost looks like she is yawning when she opens her mouth, and at times it looks like her jaws are not lining up correctly, but then they go back to normal. Sorry that this is so long, but we are all (us and the vet) at a loss for what could be going on, and we don't want to lose her!!! HELP!!
