My 19 year old cat Winston - who has traveled all over the country with me - had lost a lot of weight. He was very low on energy and was extremely fragile and frail. After 2 weeks on your Pet Health+™ formula, he's gained more vitality, is perkier and more present and has gained some of his strength and weight back. I believe it's prolonging his life. I'm very pleased and am looking forward to using more of your formulas for myself.
