Many sites warn about overfeeding. Our sulcata is 5 and weighs 1.5lbs. We acquired her about year ago from an unsuitable situation regarding habitat, lighting, heat, diet, etc. Thx to members here we have improved those issues significantly. she is enjoying a growth spurt, a half lb. since aug., 25% increase since Jan. We recently started her on grass mix we grow from exclusively grocery greens before. We supplement her grasses with 25% grocery greens. She "cleans" her plate every night plus cactus for desert. She can easily eat a cup plus full of loose packed grass and greens.Is this overeating? She has a large enclosure 8x3.5 ft. and we now take her outside,it's warm in Vegas. Thx in advance for your help.
