I thought so too but she did. While watching her eat, I kept thinking I was going to have to go back to the store for something smaller because I didn't see any way for her to get it down. I also felt bad that she had killed a rat for no reason since she wouldn't be able to eat it. Surprisingly, she got it down.
I appreciate everyone's comments and helpfulness. I'll be feeding her a rat pup every 5-7 days and hope she continues to grow. She hasn't missed a meal yet but I want to make sure she's at a healthy weight. I'm not trying to beef her up to breed, although I would like to breed her eventually. I just want to her grow and be healthy.
Oh, a rat pup is different then a small rat. A small rat weighs somewhere between 50-80g.
