I have a cat only vet as well. She says that in vet school there is only a very small percentage of time devoted to feline nutrition and even then it comes from the pet food companies. Their reps are the ones giving the lectures about diet.
Since vets have so much to learn about many different types of animals, they don't spend much time on such a small area.
A dry food diet is not the best for an obligate carnivore. If it was, they would feed it to lions and tigers as it would cost less than meat.
A good book about feline nutrition has been written by Elizabeth Hodgekins. She holds the patent for one of the Purina dry food formulas. Since that patent, she now advocates a wet food only diet. Worth checking out.
Thanks for the info. We’re never to old to learn!
