If your cat is young with no current health issues, you may not directly notice a change now. The major benefit of giving Dr. Jones' Ultimate Feline Health Formula to a young, healthy cat is PREVENTION. This is something I always advise my clients: if you can do anything to help prevent disease in your cat in the long run, do it - with better food, fewer vaccines, and supplements. If your cat develops a serious disease such as cancer, the cost to you and your cat, both financially and emotionally, will be more than the cost of a daily supplement now, by far. Just ask anyone who has a cat now with a serious health condition, or anyone (including myself) who lost a cat before his time.
