Vetri Hairball offers an easy way to help manage shedding and normal digestive issues that are related to hairball issues in cats. Dual action is the key to this formula. The chicken liver flavored soft chews contain omega fatty acids which provide essential fats for skin and coat health while also supporting the lining of the GI tract. Added Psyllium promotes healthy movement and function through the GI tract. Lecithin, Biotin and Zinc are nutrients that support elasticity and moisture to the skin for healthy coat growth. A healthy coat is a key factor in managing unwanted shedding that can end up as uncomfortable hairball issues for your cat.
