Some cats eat whatever food is presented to them while others turn their noses up at almost everything. This choosiness is just one of the factors you need to consider in deciding which brand of cat food to give your pet. The primary factor, naturally, is how good the ingredients are, so you'll need to do some investigating. But sometimes the best cat food for your own cat also depends on other things like the state of their health and teeth, or even whether they are overweight.
