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: This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!)  My cat jumps right over it and I end up with litter kicked up all over the place.  Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter.  I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars.  Hopefully, I'll have more success with that!
Example Output: Negative

Example Input: I made cupcakes with the vanilla cake mix.  They were just ok.  They were dense, but not overly so.  So that wasn't too bad. The flavor, however, is where I was disappointed.  The vanilla flavor was so subtle that I missed it entirely, and I felt like there needed to be a little more sweetness (which probably would have also made them a bit more moist). The child I made them for only ate a few bites.
Example Output: Negative

Example Input: THE CAN DOES NOT SAY "NO ANTIBIOTICS". I called the company and asked why the can does not say this.  First, she tells me that THEY HAVE NO ANTIBIOTICS BUT the FDA won't allow them to put it on their can.  I said "lots of companies put no antibiotics on their label".  Then she said we are making a new label.  I felt a definate flippant attitude.  I felt like she just wanted me to get off the phone.  Well, I just canceled my autoship for their goat milk. I am now looking for another goat milk that puts "no antibiotics" on their label.  I know that there are some good goat milk companies that do this.
Example Output:
Negative
