[EX Q]: 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 A]: Negative

[EX Q]: I was quite skeptical about stevia at first, but tried it with another brand and thought there wasn't much difference in taste and I felt better about using a more natural product than the other artificial sweeteners out there. I then started looking at getting a bulk container and happened upon this product. I now have purchased this same product 4 times and am quite pleased. The product is a bit more concentrated and we are using less of the product in our drinks and cooking than other competitors.  The deliveries are always quick and we have not had any issues at all with the product or packaging.
[EX A]: Positive

[EX Q]: This is my second box of greenies that I have been quite pleased up until today.  I pull out on greenie and found a WORM along with larvae!! This is horrible.  I had this box for 3 months.  I emptied the box and found about a dozen more worms and was disgusted.  I couldn't believe greenies product was contaminating my dogs.  The expiration date is dated 2013 so this clearly shows that there is something wrong with this product.  I hope someone from the greenies department will give contact me to fix this.  I will be posting these comments on every doggy treat review forum/website until I hear from someone so I know that they are trying to fix it and shows how much they value their customers and product.  I don't know how long I have been feeding greenies with worms in them so my two pups will now have to go to the vet.
[EX A]:
Negative
