I've got a female rat that's a biter. Not your typical biter though.
You see her problem is she is a little over zealous about treats. Today I was taking the babies about and looking them over when I reached in she flipped out thinking I was handing out treats and ran over like a white blur, sank her teeth into the tip of my finger and started trying to pull it into her corner where she always goes to eat her treats.
My verdit is out on her, she is gone once she finishes nursing. But my question is: Should I cull all her babies? Is this behavior genetic or learned? She doesn't bite defensively, just gets confused about what is a treat and what is my freaking hand.
I bought her from a large rattery when she was already and adult, so she was never handled growing up. Should I blame it on that and give the babies a shot or cull them all?
