My female leo goes through phases where she outrightly refuses food for upto 4 weeks, it got so bad a couple of weeks ago that i had enough, i went and bought some critical care formula and fed her it through a dropper, after a week her eating picked back up and shes quite the pig now, i used to try temp her with the odd waxworm just so i knew she had something, correct set up can also be a factor, but they can go uptp 6 weeks without eating anything, is he/she losing weight?
small butterworms can often be tempting, my male loves them :-)
