Our cat is 16years old and has had arthritis for years. She walks very slowly and was no longer able to jump up onto the lounge or bed. So I put up a ramp to help her. She also has hyper thyroidism and is on daily meds for that. I started her on Rose-Hip Vital hoping to ease her pain whilst walking. A month later, she no longer needs the ramp, walks freer and has much more energy. It has helped both my pets beyond belief. Highly recommend.
