Damn. I feel this. My little 4 year old / 13 lb guy had only three stones removed last year. They were about the size of the second row. He's on Hill's Prescription diet now and I'm making sure he gets plenty of liquid. I resisted the expense of the food at first, but with his litter mate brother passing recently and not wanting him or me to go through the stones surgery again, I'm sucking it up and sticking with the canned Hills c/d food.

Good luck to your little guy/gal.
