This may be a silly question but i am so new to Geckos and here is my question. I have had my leopard gecko for about a month now and i have no idea how old he or she is. Heidie is about 6-7 inches long. Birthday present. The other day i started noticing her licking the carpet and the glass. She has a clean supply of water daily but she continues to lick the carpet. Is she needing something i dont know about. Couldnt find pure calcium without D3 so i have not put any in her tank.
