I like for Kylie to have either Nutro or Royal Canin. Tho right now due to SOF ("short of funds") she is finishing up a bag of Purina One Hairball formula. It looks like Minion is slightly longhaired ? So a hairball formula might be something you will want to check into. Have you tried The Purina Right bites Hairball control Treats? Kylie is slightly picky with her treats also and she would walk thru hot coals for those!! And also you can find at the pet store, but I found it at Big Lotz and stocked up. Stuff that looks like fish food. It is dried fish flakes, Kylie LOVES that too!
But don't get the dried fish. Kylie wouldn't touch them and Keegan vomited them! NASTY!! ugh

I really like the Royal Canin chain. They have several different kinds of food. Persian (pricey), indoor, slim, kitten, hairball, etc. Kylie is getting ready to start the indoor formula. It is designed to keep the smell down from the litter box, and reduce hairballs.
Kylie won't eat meat much either, she will eat shrimp, fish, and scallops, and a little turkey. But nothing else!! No tuna, no tuna juice. NO WAY!
Good Luck, if Minion likes what he is on, don't change a good thing, I guess!
