We think my female cat is 18 years old as I had her as a rescue 15 years ago. I noticed she was slowing up, tentative moving around on the furniture and going up and down the stairs. I have been giving her this in her food which she takes no problem for the last 6 weeks.
I have seen a massive improvement in her. She moves more freely, goes out more and even bought in 2 birds. The best thing is there is need for expensive vet medication, its natural, none toxic and she has no issues in taking it.
Well worth a try if you have an aging pet who is struggling with arthritis and the aging process.
