Tried feeding live tonight, didn't take. We started by putting some of the mouse bedding (paper towels) in the feeding tub and then putting her in it, and that seemed to get her into feeding mode--she was stretching out (she unballed much quicker than usual) and flicking her tongue. We gave her some time to get acclimated. When we put the mouse in with her, she at first seemed very interested, and followed its movements, but she never struck, and gradually as the mouse moved around she because nervous, then downright scared as the mouse got close to her. She started climbing the sides of the tub trying to get out, and so we moved to prekilled. No interest. So back in her tank she went, and the mouse went to another snake.
We're going to try some more things--we're going to the White Plains expo this Sunday, and we'll be keeping an eye out for smaller live feeders than the one we tried, and potentially African Soft Furs. In fact, we may message the mouse/rat breeder we use this week so that we can try another option on Saturday, to at least eliminate some choices. If this goes on for too much longer though, I think we're going to end up either returning her to the breeder (if they want her) or finding her a home with someone who has more bp experience. :/
