"I have a senior cat who recently began to show she is a senior. The doctor said it was arthritis and recommended that I begin to use glucosamine. I found these vitamins and not only does my cat love them. She has shown great improvement in mobility and energy. She has even turned the tables on the younger cats and does most of the instigating in their daily kitty wars. I recomend this product to anyone who has a senior kitty who has slowed down recently."
