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.

Example Input: The name of this coffee is Mahogany, in my mind a deep rich brown. The coffee flavor is deep and rich, and the color is dark brown. It is delicious.
Example Output: Positive

Example Input: I had been buying these treats for my cavachon for the past two years. He loved them.  The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats.  Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.
Example Output: Negative

Example Input: There are 4 kittens that started hanging outside the house and I started feeding them.  Rather than buying the smaller bags, this is a great value for multiple cats.  The kittens love the food and always look forward to eating it.  Shipped right to your door.  Can't go wrong with that!
Example Output:
Positive
