Q: Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.
Premise: We noticed our orange tabby, Max, was getting skinny. 
 Initial Context: Worried about him, we took him to the vet's office. 
 Original Ending: The vet was not sure why he was losing weight, and did a blood test. When the results came back, we found out Max had kidney failure. We put him on a special diet and is back to a normal weight. 
 Counterfactual Context: Worried about him, we put him on a special diet and his weight normalized.
A:
The vet was not sure why he was still losing weight, and did a blood test. When the results came back, we found out Max had kidney failure. We put him on a different special diet and he is back to a normal weight.
