Tracy, I'm so glad to hear the good news. I'm sure he's feeling a lot better now, and I hope he continues to be healthy.

Is it the diet that dissolves the crystals, he's eating? Fister had those (Hills S/D) for a while, and then changed to C/D. They are supposed to prevent cats from getting them in the first place. I think my vet said that he should not continue with the ones that dissolve the crystals, but ask your vet about this.

Kisses and headbumpies to Storm from me and the orange boy.
