Congratulations on your new little girl, and WELCOME to YT!! So glad she has found you and will now be given the love and attention that she deserves. Has she been vet checked yet? Given that she is so tiny, I would want to be sure she doesn't have any issues like liver shunt or anything. I personally would give her home cooking (chicken and sweet potatoes, or rice and hamburger, etc) to be sure she gets to eating soon. Good luck with her, and I can't wait to see pics!
