Ive had my female leo for about 6 months, and ive noticed that recently she hasnt been going in her warm hide very much. And whenever i pick her up, she is cold. Shes in a 20L tank with a hide on warm and cool side, water bowl, food bowl, plants. her temps are around 88 on warm side, and 70-75 on cool side. She eats every other day crickets and mealworms dusted w calcium 3 times a week. any idea whats wrong?
