Purina One has a good value for money: the products are not as expensive as the Royal Canin but will gladly eaten by my cats just. The quality is so because low-dried fodder as from the Lidl / Hofer / Aldi stir my cats do not (much to the chagrin of my wallet). For this I feed wet food because dry alone is on the kidneys not be healthy cats. I am very pleased with Purina One.
