Oxalate crystals are treated only with surgery, AFAIK. I suggest you talk with your vet about using l-methionine with you kitty's current canned food (or one w/o grains would be even better). L-methionine shouldn't be used without some supervision such as urine pH testing by you or your vet because it is possible to drive the pH too low (creating oxalate crystals) and you want to avoid that.
BTW, chicken breast meat has even more l-methionine than gizzards.

I don't know of any quality, grainless canned foods that are specific for crystals, but here are some good grainless canned/wet food brands (NOT all varieties are grainless, you need to read labels):

Nature Organics, Wellness, Nature’s Variety, Merrick, Natural Balance, EVO, Addiction, and Ziwipeak
