Recently, for the past two months, my leopard gecko has been going to the front of her tank and opening and closing her mouth. I can always hear her doing it, it’s not loud but she does it for a couple minutes then stops. I feed her weekly, usually about 15-20 mealworms. Is there any cause for that? She’s also been having a rough time getting the shed off her nose, I always wet her moist hide but she only goes in it for a little bit. She’s had a cut on her nose for the longest time and she’s been worrying me lately with her behavior.
