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: I consider my Sheltie to be an intelligent dog, but the noise of the toy makes him back away. And I can't tell you how many times I've "demonstrated" how to get the kibble out. He just waits until I do it. He could care less about the thing, and he's very food motivated.
Example Output: Negative

Example Input: I bought a couple of flavors from Halo's, both were not a hit with my cats unfortunately. My cats would not touch it.
Example Output: Negative

Example Input: I was excited for these. Got them on a Monday, on Tuesday I came in and my husband tells me you have to try these they are excellent. So I'm like Ok, I reach in the bag and I'm like ewwwww they feel slimey but none the less popped one in my mouth. I almost puked, I spit it right out terrible, disgusting, don't buy these. I love Amazon and buy a ton of stuff from them but these are a definite NO! I might add this was a joke to my husband because he had ate one and had to spit it out! He was just wanting to watch me eat one. :(
Example Output:
Negative
