I have a leopard geko that's is about 10 years old name lizzy. I looked in his tank to say good morning and found him sitting with his jaw wide open and sand and what could have been a cricket foot hanging out I picked him up and poured some water in his mouth to get the sand out. He closed his mouth but is very sluggish and barely moving.. the sand I put in his tank is a vita sand and have never had this problem before... He has lost the thickness to his tail that was once fat and also some body weight as well. Yesterday he was energetic and dancing in his tank as normal. Could he have a cricket stuck in his throat? Or a bad cricket that made his ill?
