I think you should give a shot at feeding it and see how it feeds, then make a decision from there. I was sold an extremely skinny and small snake recently that DEFINITELY looks like it hasn't fed... but it was at a discount, and I saw the snake as I was buying, so it was expected. She refused her fuzzy rat last week, so I decided to get her a smaller one (it was seriously the size of a small mouse hopper) and left it in her 6 qt tub overnight in the dark. She took it by the morning. It might work if you try that with your snake... just make sure the prey size doesn't intimidate her! A little smaller than normal could help with her self-esteem (so to speak).
