Cranberry extract 125mg (Vaccinium macrocarpon) contains anthocyanidins (PAC A2, PAC B2, 3-PAC) that prevent bacteria (e.g., Escherichia coli) from adhering to the epithelial cells of the urinary tract within the bladder.

Valerian extract 40mg (Valeriana officinalis) has soothing properties that are beneficial for cats with FLUTD or idiopathic cystitis.

Parsley extract 50mg (Petroselinum sativum) has diuretic properties (increases urine volume) and facilitates the removal of pathogenic bacteria from the urinary tract.

Glucosamine 84mg is a precursor of glycosaminoglycans, components of the extracellular matrix that cover the mucosa of the lower urinary tract. Glucosamine reduces the permeability of the bladder wall to bacteria and toxins.
