How often do adult Leopard Geckos shed? I have no Idea how old my Leo is - I think the person who was the previous owner was far from honest about his age and health. My guy seems to be thriving and has improved health since he has been with me. The significant health challenge we have accommodated, with feeding, is his lack of eyesight. My concern is in three months of having him he has not shed once - I have seen our other Leo shed at least three times (7 months old). I have a moist hide. Any assurance or advice would be appreciated.
