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.

Q: 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!

A: Negative
****
Q: If you follow their recipes precisely, with careful measurements, the freezer jams are excellent.  Strawberry jam is particularly appealing.  I've been warned that changing quantities of any ingredient will not have happy results.

A: Positive
****
Q: Terrible. Half of the rinds don't cook and the ones that do are gummy and shrink. Contacted Lowrey's about the defective product but they failed to respond.

A:
Negative
