I recently saw on an Investigative Consumer Report on my local news some disturbing news on these products. Multiple pets had to either get surgery or even passed away in result of improper digestion of this product. When the company was asked to comment, they declined, then issued a statement, implying that the pet's illnesses/death were a result of the owner not using the product correctly. But a Vet that treated one of the cases, says it was due to the product itself. They do not break down in the animal's digestive tract as easily as the package leads on. In some animals, it causes a blockage, which results in infection, sometimes leading to death.If you want to find out more about this consumer report, you can find it on http://www.kirotv.com/consumer/5325021/detail.html
