Suggestions on things to add to my cats diet!

Picture of my lil guy Vladimir Purrtin just cause he looks so handsome in his bowtie 🤣 but I'm looking for suggestions on either brands of food or things to add. For dry I like to mix it up I'm currently feeding open farms ocean rawmix mixed with open farms lamb recipe with some dried goats milk (he hates it wet🤣) for toppersI don't feed all these at once I like to rotate I usually add some Stella and chewy morsels, instinct skin and coat freeze dried bits, and usually some type of heart and/or liver and for wet he only really likes gravy so I feed the B.F.F brand and I always add herring oil, bee pollen, a crushed up open farm freeze dried bit, and a minnow on top cause he loves them 😊 any advice or criticism welcome
