Has anyone tried "Urinary Tract Irritations" by Natural Pet Pharmaceuticals? My male cat, Mittens, 3 1/2 years old, slightly over-weight maine coone mix, leaked a little urine ( about 1 tablespoon) in his two resting spots. Other than that, he's eating and acting fine. I was thinking of trying this medicine after reading reviews on Amazon. Any suggestions please? (He's on mainly a wet diet of fancy feast, natural balance and friskies with a teaspon of Nat. Bal. kibbles on top which he must have). I don't want to take him to the vet because of the rabies vaccine, which is required every year in Tenn.
