I began using this because my cats were vomiting after mealtime, and it was getting very tiresome with all the cleanup. I have 14 cats, and half of them have long hair. I understand the occasional furball, but this vomiting was too much. I labeled this review "in process" because they don't receive a full scoop full. They receive wet food twice daily, but they are small portions - not large enough to accommodate a full scoop. I am still trying to increase the amount of powder I sprinkle on their food. BUT this additive has SUBSTANTIALLY reduced their vomiting. They also have dry food available to them. Originally, they weren't crazy about it, but they got used to it! I think it smells like cooked celery.
Bottom Line: Yes, I would recommend this to a friend
