feline arthritis

Have you tried Syn-Flex for feline arthritis?
My 16 year old cat suffering from arthritis Kelsie. I tried Cosequin for cats. That was fine, but she was still in pain. After a little research and talk to a veterinary technician, but I refuse to your veterinarian about prescription drugs in this moment due to side effects. Arthritis has been the only disease that is not a bad tooth that had to be removed. She has done wonders for its age. Syn Anyway, I tried-flex because I read that better pain control. It is safe for cats, dogs, horses and people, and almost no side effects. Kelsie is doing very well. She is playing again and is much happier and it has been over a month. I put this "question" because I wanted others who have cats with problems common to know about it. I looked for a long time before I came. My husband is also, and he really likes. It costs about $ 28 for a bottle.
Thanks for the information. This was kind of put this there for the benefit of others.
