I fed primal as a primary portion of their diet for a loooong time...and then they changed how they processed the food which did something to it so now the boys barely eat it. They flat out refuse to eat the chicken, will nibble on the turkey, and occasionally eat the beef. (I've tried other flavors like Rabbit and Quail and they were a big waste of money.) Currently feeding Radcat now, but after a few months it seems they're losing their taste for that. I try to rotate with other things (Weruva, Instinct, Stella & Chewy, Tiki Cat, Lotus, homecooked chicken, etc) so it can't be that they're bored. They get better food than I do lol Currently have SmallBatch Rabbit (they refused to eat the chicken) and Answers chicken on order, we'll see.
