If it helps at all, a kitten should gain a pound a month. You should have gram scale, it has ounces on it. Make sure she is not gaining too much. Her urine should be light yellow and her poop brownish. If it is green, she is eating to much. Don't switch to stage two untill she is about four weeks. Also try introducing her (a little at a time) to baby food (gerber lamb) at about four to five weeks old. You sound like you are doing great. Please keep us posted and keep up the good work!
