Interestingly, this also holds for cat food. People are often willing to pay a premium price for the food of their pets, while in the end they and their pets get to eat low quality processed stuff.
If I were to cook for my cats, they would want meat, chicken and bacon every day.
Also, those people that try to feed their cats/dogs "vegan" or "vegetarian" are terrible human beings and don't deserve their furry friends.
Nearly all of the good foods had premium pricing, but not all of the premium priced foods were good quality. On the other hand, few to none of the mid to low priced foods actually were 'good'.
