we don’t have that same instinct about our animals. So it really is a challenge to make sure they get the proper food.

This is the source of our extremely low grade disagreement.
The properly motivated have access to a plethora of resources from which to choose. It is not a challenge to find good information at all, if one is willing to put in the effort. A good place to start? Your vet. I am blessed with a great one.
Actually, part of the problem *is* the challenge of finding good information. Most of the nutritional information out there is complete trash. I find that nutrition is an area where quackery and emotionalism run high, and science takes a back seat. That is true whether you are talking about human or pet nutrition. I have often observed that, ironically, people who are the most motivated to want to consume a "healthy" diet or feed one to their pets are the ones who fall the hardest for the pseudoscience. They may put a lot of effort into finding information, but it is usually information that matches their biases, not information that is based in solid science.
I have also observed that vets can fall for pseudoscience.
