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: Consider Input: Please think twice about purchasing this product, especially if you have a small-breed dog. I was lured by the cute, gimmicky labeling and sold by the ingredient list, but I twice fed Merrick canned food to both of my dogs, and BOTH times, BOTH dogs were diagnosed with pancreatitis -- an illness which is dangerous, extremely painful to the animal, and which requires hospitalization. I'm not sure if the fat content in those particular cans was high, or if Merrick uses an ingredient/additive that somehow sickened both of my (unrelated) dogs, but this food made them very ill. After their second hospitalization for pancreatitis, I spoke with other folks who had stopped feeding Merrick to their small-breed dogs for the same reason -- the food caused vomiting, diarrhea, and lethargy in their pets.

Output: Negative

Input: Consider Input: This tea is very good. I discovered it while visiting in California. The moment I got home I searched local stores for it and I was not able to find it. Finally I decided to see if Amazon had it and they did and I bought two boxes. As long as they make it I will buy it.

Output: Positive

Input: Consider Input: This is an great product. The taste is great, and it works exactly as described. Superb natural sleep aid. AMAZING!
Output: Positive
