Yes Perches, Yes heated via hot water (not sticking a probe in the rats), when shes on the perch I get her to smell the prey but she just ignores it after the fact.

Today I even went to the local pet shop and bought live rat pinkies and a live fuzzy. Both were rejected. She acted interested in the Fuzzy for a good bit, but never tried anything, she just ignores the pinky 100%.

Also, anytime I have offered food I have turned off the lights just incase there is a "heat" problem for discerning food.
