It was time to order cat food again and I thought I'd give the Natural Balance line a try.  My cat loves fish, so I figured that the Tuna and Shrimp Recipe would be a big hit.  Nope.  Both cats in our house gave it two thumbs down votes - neither of them would touch it.  What finicky little critters they can be sometimes [sigh].

Ex Output:
Negative

I have been using AGAVE NECTAR as my main sweetner & in 1 week I gained  about 5 pounds! I eat really healthy & I am in great shape and couldn't figure it out, then I did some research. AGAVE NECTAR is made of 90% fructose, it is a HIGH consentrated sugar. It causes FAST WEIGHT GAIN. I'm not for sure what I am going to do with the rest of these bottles I have but I'm not putting them in my body! The worst thing is that I have been feeding it to my family, saying this is "healthy"! So do your research before you buy anything that claims to be "healthy".

Ex Output:
Negative

Unless you like salt vinegar chips as salty as eating actual pinches of salt and drinking actual vinegar, i doubt you will like these chips.  These are the saltiest & sourest chips I have ever had, and the only reason stops me from throwing these away is because I paid for 2 full boxes and dont like to waste food.  The brown chips are especially bad, besides being salty and sour, they also taste overcooked and burnt.  Unless you are the rare kind that can take this kind of extreme taste, you will not like these chips.  I actually have a high tolerance for sour taste, so I can down a bag of chips with a bit of difficulty.  But normal people, please do not try this at home.
