Saw the d-mannose included in one of the liquid cranberry concentrate products, specified for urinary health support, but wasn't sure it was cat-safe, 'til now. Already started w/cranberry concentrate. Hugo is a master of pill-avoidance & squeezing the contents out of the softgels is messier than I imagined. So, I'm soaking them in water for a few hours & they smush right up. The flavor doesn't seem to phase him @ all. Thought it rather pleasantly tart, myself! Will p/u d-mannose, shortly. Implementing your protocol. On behalf of Hugo (& myself) -Thank you! Thank you!
