Royal Canin Feline Cat Indoor Long Hair 35 Dry promotes a brilliant glossy coat, and reduces hairballs.

25% of all indoor cats have a long or a half-long coat. They spend one third of their time with grooming it. While they groom themselves, a great deal of hair drops away, of which about two thirds is swallowed. The great amount of swallowed fur, but also the length of the hair promotes the formation of hairballs.
