As your cat grooms themselves the majority of this hair passes all the way through the digestive tract with no problems. But if some hair stays in the stomach, it can form a hairball. Usually, your cat will vomit the hairball to get rid of it. Hairballs in cats are more likely to appear in long-haired breeds, such as Persians and Maine Coons.
If vomiting, gagging, retching, or hacking occurs without producing a hairball, or lack of appetite, lethargy, constipation is an issue be sure to contact your veterinarian, as this could indicate that a hairball has caused a potentially life-threatening blockage.
Along with regular brushing the following whole food supplements can help minimize the problems of hairballs.
