Vétoquinol Care's Bladder Struvite Gel (formerly Uro-Pet and Methigel) supports the reduction of repeated struvite stone formation. The gel supports the urinary tract when diet modification is not possible due to a fussy eater or with multiple animals in the house. The palatable gel contains DL-methionine to acidify the dog's or cat's urine. The gel has low magnesium content and uric acidifying properties. The dietary supplement is only suitable for bladder stones consisting of struvite.
