James Wellbeloved Hairball Formula is ideal for adult cats that are prone to hairball problems. Hairballs are formed when hair swallowed by your cat during grooming accumulates in the stomach and can?t pass on to the next part of the digestive system. Because your cat can't get rid of the hair in the normal way, he or she has to vomit it out. Our Hairball formula contains 6% of natural insoluble pea fibre, which can trap swallowed hair and carry it all the way through the digestive tract and into the faeces, thus greatly reducing the incidence of vomited hairballs. A complete dry food with the bonus that it is hypo-allergenic. With selected protein source (turkey), it is a dietetic food, excellent for the reduction of ingredient and nutrient intolerances. We suggest that the food be tried for a period of 3 to 8 weeks. If the signs of the food intolerance disappear, continue feeding indefinitely.
