Definition: 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: 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!
Output:
Negative
