I bought two leopard geckos for my son when he was 4 years old-both females. One lived for 21 years and the other is still alive at 25. We keep them fed with crickets, plenty of water, we use crushed up walnut shells for bedding, and we help her get off the skin when she sheds. I've noticed that she has been shedding excessively lately so I will give her some vitamins and see if that helps, along with spraying with water often. My son seems to think that she is getting too old and we should consider putting her down because the shedding problems will get worse she may soon not be able to see and develop eye problems and he doesn't want to see her suffer. I don't mind helping her get rid of the skin when she sheds but I am wondering if my son is right. Any ideas?
