Given the task definition and input, reply with output. 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: My neighbors have a grey cat which mostly stays outside. 
 Initial Context: I had put a bird feeder in a tree I could see from inside my house. 
 Original Ending: I was watching the birds feed when they suddenly all flew away. Then I saw the neighbor's cat hiding behind the tree. It had tried to catch a bird but they were all too quick for it. 
 Counterfactual Context: I had put a cat-safe bird feeder on a pole surrounded by our koi pond.

I was watching the birds feed and enjoy themselves. Then I saw the neighbor's cat hiding behind the tree. It was staring on in jealousy because it could not do anything.
