Caring for animals can be challenging and chameleons are said to be one of the more challenging. What I do when I notice something not quite right with any of my critters - I give it a short amount of time (usually a few days) to see where it goes. Some things go away quickly and are never seen again. Depending on the problem, I may try a bit of first aid, or I may jump right to making an appointment with a vet. If the issue resolves, I can always cancel the appointment or use it for a general wellness check and maybe a fecal.
