Thanks Zincubus!
LOL, it doesn't matter, she does what she wants.
I prepare the rats exactly the same way every time; properly defrosted, properly warmed, etc.
Last feeding she struck (which she rarely does) before I even had a chance to shake it or put it down for her to pull in her house. This time, nothing. She's a BP and an odd duck, what can I do?
She's happy and healthy and she refuses meals sometimes and fasts in the winter. That's what she does. I have given up worrying about it and just roll with it.
