My leopard gecko Sol, has been eating weirdly lately. She went on a type of fast and would only eat crickets a few times a week. When I purchased her she was around 20g or so. She now weighs in at 28-29g. All of the sudden last week she began eating mealworms again with great enthusiasm. She came rushing out of her hide to get them when I put them in. Temperature has not changed and her environment has not changed. So it wasn't a winter thing. Any thoughts?
