My cats (one dictates the diet the other follows) are on wet food only diet and after a lot of hit & miss, found Pro Plan to be the favorite in varieties of salmon….So I would find a local pet store with a lot of variety and start with 1 brand that has a lot of variety and start 1 at a time, recording what they like and don’t like. Somehow I landed in Salmon which helps (he doesn’t like any land-based meat so I early ruled out everything not seafood). I then found out that he must have variety so no repeat cans in a day. So I then had to try other brands as Proplan has only 5-acceptable types. Trying salmon only we found the Petco Senior brand and a couple of FussieCat (premium of course) to round out to 10-acceptable types that I stock up and choose from. A couple of other points: I can only use 3 oz cans (they reject ‘old’) and no cheap brands that have lots of carbs, fillers and hidden sugar for taste.
