I attempted a feed tonight but I noticed she was in the blue so I didn't have my hopes up. She perked right up and tracked the rat when I put it in. She even struck at it but missed a little and the rat got away. After that she tried to track it but long story short, she didn't eat tonight. Not a big deal, but I was wondering if she just missed because her eyesight is impaired a little. I am sure that is it but I would like to hear if it has happened to anyone else.
