Tinkle Tonic is an herbal tincture that is specially formulated to support a healthy urinary tract in cats and dogs. Tinkle Tonic was originally developed in 1996 for veterinarians who asked us to formulate a natural remedy that can be used as part of a holistic approach against feline urinary issues. Today it has become our most popular tincture formula, used in both dogs and cats to support urinary tract health and promote comfort during urination.
