It didn't work ;-( my pet Molly has been on this for about a month and to be honest there was no change. Molly is also on antibiotics to help with the UTI she has but I thought the Cranberry relief would aid in helping her as well... Needless to say, Molly had to go back on antibiotics because the natural way just wasn't working. I had high hopes but I may try the capsules instead. She did have better results when I did 2 full capsules a day in the human form.
