Mouth opening. What's happening?

Hi guys. My female jackson chameleon has been opening her mouth wide recently. Nothing was around her that could be stressing her out. I just looked at her one day and she was opening her mouth. I thought she may be hungry or thirsty, so I fed her and gave her water, but she was doing it 5 minutes after again. I don't have any pictures of her doing it because she immediately closes it when I go close to the cage, but I saw her doing this last night and tonight. I saw her doing this before she had a heat stroke when I took her outside, but this time the cage light was off. She also seems more fat then usual. I think she may be pregnant, but I haven't seen her mating yet. I don't know what to do since I'm still new to this, but hopefully some of you guys do. Please help.

Do keep an eye on her. Another possibility besides those mentioned above could be she is about to shed. They do an exaggerated yawn to loosen the skin prior to shedding. Observe her for any signs of a respiratory infection such as stringy saliva or popping or crackling noises in the meantime.

She has been shedding recently. I saw a piece of skin fall off of her when she opened her mouth. I have not seen or heard anything unusual.

My male jacksons did this about a month ago and had me all up in arms! As soon as I’d come near his cage he’d close his mouth just like yours. He was shedding around his jaws and I hadn’t picked up on it. Still keep a close eye on her.
