You said…”I live near a mountain but also in a city, everyday i get her out of her cage for a few hours”...I was asking where you live so I would know the climate/temperature there and it might give me a clue as to what’s going on.
You said…”When i try to put her back she doesnt want to so i would keep her out for a few more hours. Not sure about the temperature but we believe that she got a heat stroke so my family would turn the AC on“…I still need to know the temperature in the area where you had her out. Also, I forget to ask the species and age.
You said…”We dont have a lay bin“…is she old enough to lay eggs?
You said…”i also recently discovered that she got mouth rot and it looks kind if bad”…that needs to be looked after asap. You need a good chameleon vet for this.
You said…,”now she doesnt even want to open a single eye and she is breathing quite heavily and stopped the “coughing”” ….this is not good news.
So…please post some photos of her and the cage including the lights you have on the cage…and the other info I asked you for.
