Your statement is interesting.
Many cat breeders have found their breeding stock stays healthier when fed a raw food diet. Evidently potency drops when felines are fed cooked food as opposed to raw. And forget about feeding kibble! The dry food is only for the convenience of pet owners, or just for an occasional meal.
That gets into some interesting variables.
That is, cats are both carnivores and their physiology is very different from humans, or canines, for that matter.
As carnivores, their metabolism is oriented to raw meat, and feeding them anything else will likely cause problems.
Humans and canines, however, are omnivores, mostly meat with some carbohydrates, but though we have been eating (more than optimally) too many carbs for thousands of generations, we still haven’t fully adapted to healthfully eating more than a minimum amount.
But this is yet again different from the increased nutritional availability of cooked food vs. raw. Better nutrition makes for an interesting paradox, in that people have more energy to get more food, but don’t need as much food, so more energy is committed to reproduction. And you start getting into Malthusian curves.
The last variable is parasites, which weaken the system. Humans used to be infested with a litany of parasites, but over time, we have eliminated so many that we have even more energy. And it is now suggested that our immune systems had adapted to all these parasites, and is confused by their absence, which results in several auto-immune diseases.
But back to feline physiology for a while. Cats are so completely different from humans and canines that many drugs you would think would be universal for mammals, aren’t. For example, when cats are given an injection of morphine, they do not get a sedative/painkilling effect. Instead, it is like injecting a dog or human with amphetamines. Morphine will turn a friendly house cat into a shrieking ball of fangs and claws.
