My vet told me that all the hairball remedy for cats and ferrets, etc. is basically the same, flavored Vaseline. He suggested I just buy Vaseline and give it to them daily. If their poops are too Vaseline like reduce the amount. I give it to my guys at bedtime when they go into their cage for the night. That way no Vaseline poops outside the cage. I hope that helps!
