Kibble wasn’t invented for your cat’s health. It was invented in the 1950s for human convenience. Before that? Cats ate scraps, hunted mice, and stayed naturally lean. Obesity was practically unheard of. So what changed? The process is called extrusion. To make those crunchy nuggets hold their shape, manufacturers HAVE to add a ton of carbohydrates. Usually 30-50% of the kibble is carbs. Here’s the problem: cats are obligate carnivores. Their bodies evolved to run on protein and fat, not carbs.
