I picked up a 2000g female in January. I've been offering her 200g f/t rats every Sunday. I've been yet to be successful; I've even tried using tuna to scent the rat; and she still pays no attention. I have also tried offering her 40g weaned rats with the same result - and the same with large mice.

My ambient temp is around 75; my hot spot is 95; my cool side is around 75; my humidity is around 65%

I'm going to pick up a live rat for next weeks offering, and was just wondering if anyone knew any other tricks?
