I have a 4 year old female Leopard gecko. She has not eaten in two weeks now but has drank water and defecated ordinarily. I house her on sand but shows no signs of impaction, no discoloration on stomach nor sand in feces. I feed her mainly on mealworms with crickets as well although crickets not as much due to availability, please help, any would be appreciated as their is no herp specialists in my area.
