Recently there has been a large "recall" of pet food due to accidental toxic substances being found in the dog and cat food items. Pet owners around the United States have joined in a class action against various pet food suppliers. There is no credible evidence that these toxic substances were purposefully placed in the food. If you were the attorney for the pet owners, what would be your two main causes of action (basis for a lawsuit) and explain each element and state if each element has been satisfied or not and why/why not.
