My Mexican Red Knee Not Eating!

I have an awesome 2 1/2 yr. old female Mxican Red Knee I've had since this past May & so far she's only devoured 2 crickets! She is (tends) to be a fussy eater I think. Would you suggest offering "Hades" something different, like a pinkie mouse, or a pinkie rat ( live or frozen), or a superworm? Other than that, her abdomen's nice & plump, she sits upright & she still kicks her urticating hairs at me when annoyed when I attempt to hold her!

Thats tricky. Some spiders take it hard if they have changes in their enviroment (I had a curly hair that would'nt eat for over 6 months).
If your T shows "normal" behavior and her abdomen (butt) is full, I would'nt be to concerned.
I feed all my T's crickets, even the big guys. Food is more a preference. If you like pinkies and your T will eat them, then thats fine to. More importand is, that your feeder animals are gut loaded (pinkies dont count of course ).

It's also possible she may be approaching a molt. Some t's may fast for several months when they are prepairing to molt.
