I have a small sulcata, probably around 4 months old, and he is pretty picky. Ive heard on many sites that they need about 80-90% grasses but he probably only gets around maybe 10% grasses. The grass is "Pet Grass" the kind you get at pet stores, its organic and has no wheat gluten. The rest is composed mainly of romaine and leaf lettuce, dandelion leaves and hibiscus flowers. I do give him his calcium with D3 supplement too. Is that an ok diet? Everyone online seems to feed their sulcatas mosty if not all lettuce. So im just making sure.
