Bladder stones are not found in every case of urinary tract infection. However, the chance that struvite (the most prevalent sort of bladder stones) will form in the urine is tremendously increased. The infection causes a rise of the pH in the urine. When urinary pH is high, there is an increased chance of struvite formation. To prevent animals with a urinary tract infection from getting struvite, it is recommended to feed a struvite prevention diet.
