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.
