Try Angel eyes for her.
It's a powder you put on their food, like Muddypaws said she's not getting enough of something (I forget what though).

Thanks for the advice, Buttercup, but that kind of thing is just not available here in China... The peroxide is helping and she seems to be making less "goo" as well possibly due to a better diet since my friend rescued her from living on scraps at the work canteen!
