Cheaper Brands are False Economy
Many first-time cat owners, in an attempt to hold down expenses, buy the cheapest foods they can find for their cats. This is false economy for a couple of reasons. First, studies have shown that cats eat as much as they need to get the nutrients they require. Therefore, they might eat twice as much of that generously-carbohydrate-filled store brand to get the nutrients they need in a normal feeding of premium food. Second, the continued feeding of substandard foods over a period of years will heavily contribute to, or even cause, serious medical conditions that will require expensive veterinary care. For these reasons, the old maxim, “You get what you pay for,” is particularly true where it comes to cat food.
