In the past I've had cats who loved Laxatone, but not Freckles. It would end up as gobs in her ruff. I put Vaseline on my dry feet in the morning, and one time Freckles started licking it off my finger. Vet said that was ok because its the main ingredient in the hairball products. So every couple of days I give her about a teaspoon worth. Seldom have hairball problems now.
