If it's crystals, it can be remedied with a food change, but they have to know what kind of crystals to find out what's the right kind of food. Smudge had struvite (magnesium ammonium phosphate) crystals, and was put on c/d, which he thinks is delicious, and hasn't had any urinary trouble since.

There's a joint supplement called Cosequin which also strengthens the inside of the urinary tract, to keep irritations from escalating into blockages.
