Some time back I feed my cat some semi-dry food which was not very nutritious but them I looked at their health and changed it.
Now I feed them dry food like cereals, the brands are go-cat and whiskas.
I also feed them sometimes food from a can, the brands are felix and rufus.
But they never seem satisfied with what I feed them.
They always want the canned food which is a little more expensive.
But they only have it twice a week. What should I do to keep my cats happy besides give them canned food all the time?

You can't keep them happy. We have always had the same problem, even with rescued cats who you'd think would be grateful for every morsel we hand them.

I notice our cats will eat a mouthful or two of the fresh food from a can and then walk away as if in disgust, but will return in a few hours to eat more once it has dried up. We put out a bowlful of dry catfood (and fresh water) for them to graze on (so they won't starve, haha).

I decided they play a game so we open more cans of food for them.

I do usually give them some milk when there is not tinned food in the house.
But they know I won't give them more so in the morning the dried food is almost finished

When I open a can of tuna or salmon for the humans, I squeeze out the juice for the cats and even mix in some small white bread bits. When we have chicken or turkey, I pick around on the eaten pieces and pull off any meat bits for the cats and add that and some bread bits to any broth that's left.

I don't think I can do that because when ever they eat non cat food then they throw up.

Then try just the tuna or salmon juice? (I buy it packed in spring water.)

Wow! In 60 years, none of my cats ever threw up chicken bits.

Well my cats are 15 years old... in human years and that is no lie.
They are brothers. And thanks for the suggestion
