When you're looking at a bag of dry food, what would the ideal or max be that you want for fiber? Is there a max? I know more fiber is better, which is why sometimes dog foods are better than cat foods, but how much would be too much? I was just curious about it, because the Chicken Soup brand tends to have about 8% or so (in both cat food and dog food), where a lot of others that I looked at had between 2 and 4%. I'm sure that level can be higher when it comes to other foods. Is there a standard good amount, or a cutoff amount?
