I have a female spider that I recently acquired. I've tried everything under the sun to get her to eat rats. She refused to eat rats. After watching her lose about 10% of her body mass, I decided to try a hopper mouse. She ate it without hesitation. I do believe she has claimed herself to be my most finiky eater. All my others will eat anything that comes into their cage. She, however, must eat when I'm not watching and apparently, it must also be a mouse.

I know a lot about feeding mice to corn snakes, but not a whole lot about feeding mice to BPs. Is there a certain rule to follow that's different from the 10-15% of their body mass? Also, is it better to feed her larger meals (like 2-3 mice a meal once she outgrows just one mouse) or just one mouse (like a jumbo mouse) in a shorter span. For example: is it better to feed her two jumbo mice every week or one jumbo mouse every 4 days for the rest of her life? I want to make sure she's getting adequate nutrition for optimum growth.

And a final question, is it possible that she will decide a rat is good enough to eat? or is her diliberately turning her nose to them but gobbling down a mouse a sign that she will never like rats? I don't mind feeding her mice as long as she'll eat them, I was just more curious than anything.
