Discharge... Again!

I have a female chinchilla, 10 years old. Poor little babe's genitals and tummy and wet today and it looks like the discharge is coming from her vagina. I didn't notice any smell when I picked her up to check her out. Looked a bit like translucent gray, but I'm guessing that could be from trying to dry herself in a dust bath.

This is the fourth or maybe fifth time this has happened. The first time was last June. Each time her appetite comes and goes but her energy is fairly normal...
