I am currently choosing to feed my kitty feline fayre as its 60% meat and its obvious meat, todays pilchards food was literally some pilchards in jelly. Its only the same price as whiskas too so I am happy.
I looked into feeding supermarket brands and decided to try not to as they contain cereals (why are these given to a carnivore) and little of what we would call meat some only state "minimum 4% meat" which seems a bit odd, if they were proud of what they were selling they would state exact meat content as some other brands do. Like Bovita who state 80% ish meat for example.
As long as they are complete and your cat can handle cereals they will get everything you need!
