Not for every Maine Coon
My adult Maine Coon Tom cat has been on Royal Canin Sterilised, since he was sterilised approx 6 years ago, and he loves it. Ages ago I tried him on Royal Canin adult Maine Coon and he wouldn’t entertain it. Recently I thought, tastes change with age, and I might be doing him out of what’s best for him, seeing as it’s made specifically for Maine Coons, so I bought a small bag to try again. Exactly the same reaction! I put 12 pieces of kibble in his dinner, and after he’d finished 12 remained!
