My panther chameleon made a coughing / sneezing sound and I took him in to the vet for a culture, $150 later for a culture, there were some pathogens and I had some liquid antibiotics to administer. I am not sure if I gave him enough, but he still occasionally makes that coughing / sneezing sound.
When I listen to him breath, I do not hear a crackle sound, I do not see foam in his mouth, and he has a healthy apatite, active, and otherwise seems normal.
Is there a youtube video of all the normal chameleon sounds?
