Since you're feeding f/t, maybe she's biting the "wrong end" because it has more scent. So try using your feeding tongs to pinch-damage the nose first, see if that helps?
But since she's a BP, she probably targets more on the heat anyway (& mouse butts are bigger than mouse heads, lol). If she was a human, maybe she'd be dyslexic? :D
Hey, we're all different...it would be so boring if we (& they) weren't. :snake:
