Instructions: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: My one year old cat ate a few of these and seemed lethargic. Two weeks later I gave him a large helping of these and I thought he was going to die. He laid around and would not eat or move for two days. I will not feed him these again. Same thing happened to my parent's cat after eating the salmon variety.
Output:
Negative
