Treatment
Do not attempt to treat a respiratory infection by yourself. Make an appointment with a certified reptile veterinarian, who will prescribe an antibiotic and may require a culture to determine the exact cause if the initial antibiotic doesn’t work.
Meanwhile, check your enclosure’s temperatures and humidity with digital thermometers and hygrometers. Analog (stick-on) devices often provide wildly inaccurate readings. If your chameleon is in a glass enclosure, switching to a mesh enclosure will help prevent the symptoms from returning.
