Noticed that, recently tried to feed BP F/T rat. If she doesn't take it then I leave it with her for a couple minutes. Then, I take it out and refreeze it before it gets "nasty rotten" and then the next time I feed her I use the same one, and this last time I did that, she struck at it andintestines everywhere!!! Yep, good thing I watched Wrong Turn Dead End a lot, my stomach was prepared for that mess!!!
