Bests & Worsts Reviews from Amazon

On the recommendation of our vet, we have used Science Diet for years. We have been ordering this particular product via Amazon for a few years now. We are very unhappy. When we made our regular order back in February, there was a note with the new bag saying something to the effect "same great product, new look." Well, not only has the bag changed, but so has the food. I wish I hadn't already thrown out the old, empty bag. The color, shape and smell is different. The cats were suspicious, but they ate it. Then, they started vomiting on a regular basis. Not the typical furball stuff, but after eating. We stopped feeding them the food and the vomiting stopped. Unfortunately, we are stuck with an expensive bag of food, because we missed the return window. I don't know if this is some bootleg, rip-off or what, but I won't be ordering this food again. We are very unhappy customers, and we are GONE. If I could give a lower rating, I would. Shame on you Science Diet! Why mess with a product that was working? To save a few bucks in production? Done, done, done!
