Ex Input:
Are your cats getting sick? Mine were vomiting and I finally traced it back to the salmon cat food. But it's not the salmon, it's the dye they put in the salmon. Some cats simply can't tolerate it. Three of my seven were that way. If you see this happening, there's a pretty good chance that your cat has an intolerance to the dye as well.

Ex Output:
Negative

Ex Input:
I ordered this saffron after looking at seller feedback and assumed that since this is expensive it will be premium quality. But only after i put it in water for sometime, then the color of the flakes changed, and I realized that its a fake one. Dont waste your time on this.

Ex Output:
Negative

Ex Input:
Just had this to make a PB&J and I was really just eating a jelly sandwich. I guess it would be ok to mix into a smoothie (maybe), but I didn't think it had any flavor at all.

Ex Output:
Negative
