How much of a can to feed?

Hello! I have been recently hitting a dilemma with how much to feed my cats.

I recently discovered the “soup” method and it’s a real hit in our house. But in my research of the “soup” method, i began to see how much other’s were feeding their cats. For reference i buy the 5 or 5.5 ounces of any cat food i get. It’s bigger and I have two cats. I would normally feed them the whole wet can in the am, split between them on what i feel is appropriate on size. (i have a tsb i use so its actually down to a measurement but i wont bore yall) and then split a cup of food between them for grazing and then the bag feed recommendation at dinner time/over night grazing. They get freeze dried hearts, other toppers, and probiotic daily as well.

Now i’m not worried about their weight. Vet says they are good! One babies a little chunky but anytime we put him on the weightloss food he looks.. sickly.. so we stick to this schedule and hes healthy. He’s part mainecoon i expect him to be bigger.

But how much of one wet can do you feed your cats? would you say i’m over feeding? Possibly under feeding? It took a second cat to get the first to accept any food that wasnt dry kibble, so now that he too enjoys wet food i’m just trying to find that healthy balance. Thanks in advance!
