I don't have a gram scale but she is about 3 ft, couldn't see her being much over 800 grams. I work 3rd shift and I'm off tonight so I will be able to supervise. She is still passing urates so could constipation be possible? Also could you point me towards a good gram scale? Tried Wal-mart and such, maybe I'll just have to order off RBI? Maybe I'll just take her in to work with me and weigh her on the cash register
