Highly recommended for aging felines
I noticed a big change in my 15 yr old male feline after using this product.  He had nothing wrong with him that was known, perhaps weak kidneys a bit bc he drinks a lot of water, but in general he is in good health for his age. But it took about 6 weeks of daily use before I noticed a big change in his energy level. He no longer sleeps much during the day as he had been, is outside more often, lopes around the backyard & house more and is even fighting with other cats again!  BIG difference. I highly recommend this product, but you have to dose it correctly and give it time.
