What the heck???

[Zoe]

Okay, lately my female IJ (my little one who as of now has not eaten a rat - has only struck at scented ones) has been quite interested in rats, but always drops them upon constriction.
She hasn't eaten since early July.
Now, I offered her a live young rat the other day (a little smaller than a small, I guess. Still quite young). And she grabbed it, constricted it loosely, and dropped it. The rat was unimpressed but unscathed.

I really don't know what is going on or what to do anymore! I don't know if she will ever develop any more interest in rats! She is getting quite skinny, too, I can see her spine now. She is not in any mortal danger of dying in the next few days, but she is definitely on the thin side. Now, I have a few courses of action. Should I:
a) keep offering scented rats every week
b) give in and give her a gerbil
c) give her a rat scented gerbil, and then a gerbil scented rat
d) other (explain).

Any insight would be greatly appreciated!!!
