Humans can be perfectly healthy, and in fact are often more healthy, eating a vegetarian diet. That is an example of an omnivore.
From what I understand, humans who are vegetarians or vegans have to add some supplements they need that are found in meat and not in vegetables. That is, eating only the vegetables without the supplements causes a deficiency in humans.
Dogs are omnivores and that is the perception of a number of scientists, including observers in the field. Such as the lady I read of that tracked coyotes through the Adirondack and analyzed their diets through their scat.
But I have stated that cats are obligate carnivores. Maybe I'm wrong. Maybe they are a little bit omnivore, too. Misty lived another year on Purina NF, as in nitrogen free extract, as in protein from vegetable matter that did not contain or involve the release of nitrogen. See, when you consume animal protein, nitrogen is released and filtered out by the kidneys and passed out in the urine. When the kidneys don't work so well, the nitrogen backs up in the system, creating lethargy and nausea. Eating the NF gave her protein and allowed the kidneys to have an easier time. Out in the wild, she might not have eaten processed vegetable matter that could give her protein and eased up on the kidneys. She would have died a year earlier, perhaps. I could have fed her as a truly obligate carnivore and she would have not lived as long. So, under the new math, she was 74 when she passed on. Under the old math, she was 119. Are there any 74 year-olds or even any 119-year-olds that don't have an organ slowing down?
Of course, out in the wild, she might not have lived long. Run over by a car. Eaten by a bigger animal. Dead from parasitic infection or complications of birthing a litter.
Again, she lived for 16 years on Delicat and 1 year on Purina NF, making for a grand total of 17 years.
My friends who's adopted daughter is our goddaughter have a 17 year old white Tabby named Myra who is still living on Science Diet K/D. It's the only thing she can eat that doesn't come back up that she likes. And she still has what it takes to bug you until you give her the proper attention and respect.
