Hopefully she stays back on feeding for you. I've never really had any snakes that were problem feeders, but I do have a scorpion that likes to skip meals(though its like really fat). I was worried about my Rufous when I first got him, but I managed to get him to eat, he refused the meal the first week, then the second week he did also, so what I did is I put him in a brown paper bag, with 2 F/T pinkys(one of them I cut the skin and pulled it off the head a bit) and then I put a live pinky in there, then put him in and folded the paper bag over, and I checked it 20 mins later and the little booger ate all 3 pinkys(he was only suposoto eat one). So try that your next feeding with your western, put the frog in there, and take whatever you were feeding him prior to frogs and fold the bag over and put it in the tank and check back, see if that helps him eat. When I had a western hognose thats the only way she would eat is if she was put in a brown paper bag so it was dark. Make sure the paper bag is about the length of the snake.
