Has anyone ever used the product Pet Alive UTI Free? It is a homeopathic herbal formula to control urinary tract issues in cats. My 8 year old female just had her 2nd bout w/UTI in the last 3 weeks. My vet says the product is hog wash but there are many people who swear by it. My cat has never before had this problem, and my vet has now switched her from Iams Weight Control (which she has been on forever because she loves to eat!) to Royal Canin Urinary SO 33. I can not afford $175 every two weeks for vet bills and meds, so if this happens again I'm thinking about trying UTI Free. Anyone have any luck with the product?
