Is there a hairball remedy that is flavorless and odorless that can be mixed into food like Miralax? Emma used to like hairball gel but won't touch it now. She won't touch raw egg yolk or powdered egg yolk. She does not eat treats so please don't suggest hairball chews or anything. A product that is poultry-free and IBD-friendly is a plus because Leroy will lick Emma's bowl clean. Would digestive enzymes be any help?
