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: Are your cats getting sick? Mine were vomiting and I finally traced it back to the salmon cat food. But it's not the salmon, it's the dye they put in the salmon. Some cats simply can't tolerate it. Three of my seven were that way. If you see this happening, there's a pretty good chance that your cat has an intolerance to the dye as well.
Example Output: Negative

Example Input: Growing up on Oreos and milk is common. So I was taken aback with the brand extension of Oreo's to cakesters. And while I had low expectations, I must say these are better than normal Oreos. Although I can't say it'll beat the combo of oreos and milk, these are fantastic treats and relatively guilt-free. If you like cake and like Oreos you can't go wrong with Oreo cakesters. The filling will bring you back to your childhood while the cake will provide you with a whole new Oreo experience. Certainly worth a try - guaranteed enjoyment!
Example Output: Positive

Example Input: I am so please that I was able to get the tea from Amazon. I was pleased with the service. Sinus Buster Herbal Tea is very helpful and it gives me great relief with my allergy. I have been suffered with Hay Fever Allergy for the past 20 years or more. First time I find a medication which is natural and no side affects compare to other medication for allergy. I discovered the tea at a farm market in PA on a bus ride with my church. At first I was hesitated to purchase the tea, but somoeone who was in the same but I was, told me to buy the tea because she used it a year ago, and got great relief from it with her allergy. Thanks, MC
