Crystal is a finicky eater so I cannot put more than a little sprinkle of the powder on her food. She will only eat canned food with gravy so she only licks the gravy off. She is 16 and not very active. Her black fur is shinier but there has not been a dramatic change in her activity one way or another. Will continue to use it because I am hoping it helps her since she is such a picky eater.
Bottom Line: Yes, I would recommend this to a friend
