I have two senior cats (12 and 13) and have been trying to do some research into what brands of canned food are the healthiest for them. My vet said canned is definitely healthier than dry, and that I should look for high protein/low carb foods with low amounts of by-products (vs. muscle meats).
I left the vet thinking I could just do some Googling and find the best brands, but instead became more confused by all of the data and math, and am having a lot of trouble finding info that isn’t biased (i.e., aren’t manufacturer web sites or blogs sponsored by brands).
Before I go further down the rabbit hole, has anyone done the math or otherwise knows which specific brands/flavors are objectively the healthiest for an older indoor cat?
