Our take
Hill's Science Diet isn't flashy, but it's what vets actually recommend when your cat has health issues. If your vet says 'feed a quality food,' this is what they mean.
If you ask any cat-focused Reddit community what to feed your cat, Purina Pro Plan comes up first, every time. It's the rare food that vets trust AND cats actually eat.
