Our take
If you want one brand that vets trust, Reddit endorses, and cats actually eat, Pro Plan is it. It's the rare food that wins on science and palatability.
Royal Canin is what your vet actually recommends when your cat has a real health issue. It's not the flashiest brand, but the clinical formulation is unmatched.
