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

This is ridiculous.  The best gourmet ketchup I have ever tasted.  It is pricey, but wow..love this stuff.  It would make a great gift for someone who is hard to buy for but loves their ketchup.  Yummy!

Positive

I cannot say how much I love Kettle brand potato chips. Kettle brand has a large variety of unique flavors, and the quality of the chips themselves blows all other potato chips out of the water. The ingredients list is printed on each bag and the only thing really bad for it is the oil they are frying the chips in. I love that these aren't filled with nasty chemicals. I ordered the cheddar and sour cream krinkle cut ones which are great but I was torn between the <a href="http://www.amazon.com/gp/product/B0048IFUSC">Kettle Brand Potato Chips Fully Loaded Baked Potato, 2-Ounce (Pack of 24)</a> and the Jalapeno flavor. While I know the jalapeno flavor is good but this is way better. They include liquid smoke instead of actual bacon which I'm fine with since I've a vegetarian. I ordered this to give to guests coming from out of town for my wedding this spring and I can't guarantee how many I will have left. My fiance and I love these. The packaging is perfect for anyone who is giving these to kids to take for school lunches, or handing out in gift bags, even just for portion control.
