Royal Canin Hairball Care Food has been specially formulated for adult cats from 1 to 7 years of age who are prone to hairballs. Cats spend 30 percent of their time grooming with up to two-thirds of hair they shed being swallowed during grooming sessions. This can lead to hairballs in the digestive tract. This exclusive anti-hairball complex helps your cat eliminate twice as much hair by natural digestion. It is formulated with an exclusive blend of fibres including psyllium and insoluble fibres, which help to eliminate swallowed hair naturally. Triangular shaped kibble and texture promote chewing to help reduce plaque and tartar formation.
