Eye caps can reduce vision, and most of my BPs going into shed will miss because of them, which is why I don't feed them in shed, I wait until after.

Also, eye caps, if left on for too long can do permanent damage to the eyes.

I would suggest leaving a F/T rat or Pre-killed in with her, she'll probably take it and that way she won't need to strike, or if she does it's in a safe area.
