- Royal Canin Gastrointestinal Hairball is a complete dietetic feed tailored to meet the nutritional needs of adult cats suffering from digestive sensitivities and recurrent hairball formation. Swallowed hair can build up in the digestive tract, causing discomfort, regurgitation, and transit issues. This specialized formula features a precise blend of soluble and insoluble fibers—including psyllium husk—which acts as a natural brush to gently move hair through the intestines and eliminate it through the stool.Enriched with highly digestible proteins and vital prebiotics, it actively supports optimal digestion, gut microbiome balance, and smooth intestinal transit. Additionally, it contains a moderate calorie content to prevent unnecessary weight gain and is formulated with the S/O Index to promote a urinary environment hostile to the development of harmful struvite and calcium oxalate stones.
