I think you should of been weighting the snake and if the snake was losing too much weight then a trip to the vet is the correct thing to do. but if the snake was decent size and wasn't losing weight, I think you panic and put your snake thru a stressful day at the vets. and if she was getting ready to go back on feed again. It might be longer now with the added stress. I had a snake that I had to give injections to, every time I came into my snake room that snake knew that shot was coming and went into a ball. she didn't do this before getting the shots and now many months later doesn't ball up when I enter the room. talk about stress, she didn't eat for a couple more months after the shots.
