Vet Water Urinary Formula is especially conceived to help prevent urinary problems in cats. Its formulation is based on a preventative approach.Cats are extremely sensitive to tastes and smells, and particularly to acidic tastes because of the large amount of acidity receptors on their taste buds in their mouths in general. Because CATWATER-Urinary Formula is acidic in nature, with a pH between 6.2 and 6.4, cats will especially enjoy drinking this water. 4L.
