I'm concerned about the above statement that you're "only feeding her in the afternoon".
If she's just 9 weeks old, she should be fed 3--4 times every day, unless you're free-feeding her? She should also have water available at all times, particularly if you're free-feeding her dry kibble.
Sorry for my confusion!
If Ginger is only getting one meal a day, that could be the reason she isn't pooping very often.
I'm just concerned about your statement. Please clarify.
Hugs!
