Surgery may be the next option if he won't eat the prescription diet. Discuss other diets, both canned and dry, with your veterinarian first. It may take several weeks to months to fully dissolve any stones or crystals. Try to get him to drink as much water as possible to dilute his urine.

    Thanks for the additional information! In general, cats with a history of bladder stones benefit from feeding a canned-only diet to help keep their urine from becoming overly concentrated, as this can increase the risk of stone formation. Depending on the type of stones he has had in the past, it's possible that any over-the-counter canned food diet might work. In other cases, certain ingredients may be recommended to help change the pH of the urine - but this depends greatly on the type of stones (struvite, calcium oxalate, urate, etc.) that he had previously, so I'm not able to give any specific suggestions for this without knowing exactly what his diagnosis was. Routine monitoring of the urine (urinalysis and bacterial culture) may also be recommended as part of a plan to prevent further stone formation, depending on the stone type. I would recommend talking with your veterinarian to see what he/she would recommend for your kitty as an alternative to a prescription urinary diet - they should be able to make some specific suggestions based on his medical history :)
