I've decided the rat was too big. So I'm not going to feed her. I actually do buy them live the kill them. She won't eat FT yet. I tried FT at first but she wouldn't eat them so now I'm doing pre-kill to see if this will help. She eats everytime I offer unless it's FT. If I do FT she won't eat it but soon as I put a live or pre-killed she immediately attacks as if she were a parana that smelled blood.
