The following comes from Anindita Roy on Quora:
“I have no idea who these weird people are saying wet food isn't good for cats or are like McD burgers, lol. Please ignore them. Sheba perfect portions are actually one of the best wet foods you can find in that price bracket. It has only named meat and some by-products (which means organs and glands which anyway cats eat first in any animal and does not mean hooves or dead animals like some idiots will tell you), has good protein-fat-carb ratio, good amount of calories for a less amount of food (you need to feed only 4 servings if you are only feeding them to your average sized cat) and has no grains or potato at all and has low carbs (7%). It's above average even compared to much more expensive cat foods like Wellness and Weruva. If it's what you can afford and your cat will eat readily, then just feed that. If you can afford more expensive food, then do that if your cat will eat it. Even fancy feast classic pate are good grain free food (not the other ones which have loads of wheat and carbs) if your cat will eat it. However, Sheba is a better brand imo as it has no artificial flavors. I feed my cats both Sheba and Fancy feast pate along with some high protein grain free dry food.”
That's a great answer. However, canned food isn't the best food for humans, is it? Then why would it be for cats?
Canned cat food also tends to contain too much phosphorous:
The best food for a cat, is whole mice or birds. So how to mimic this with food from the grocery store? I intend to learn and update this article.
My solution in the past, when I had an indoor/outdoor cat, was to teach him to eat his kill (he didn't know how). He brought home a bird, and I plucked the feathers while he watched with great interest. Then I cut into the bird with a knife to expose blood, and put the bird on his plate. I had a guest room which became his office (the killing room). I had to vacuum the feathers and pick up an occasional beak. I also offered wet cat food and also let him eat whatever I was eating if he wanted some. If there are ingredients that are toxic to cats, throw them out of the house.
For those without the option of having a relatively safe outdoors for a cat, and limited time to indulge in preparing your own cat food, an adequate compromise may be to vary the diet with all of wet, dry, and human food. Prepare the human food with healthy ingredients for both of you, and set a dinner table for two, or three, or four, or…
