I’ve heard low in magnesium is good for those with struvite stones or that an acidic diet (like raw) is better to prevent struvite stones, but what kind of diet is good to prevent calcium oxalate stones?
Thanks Carol, but that vet stuff is horrible. It contains artificial ingredients like the chemicals BHA and BHT which cause cancer. Trading stones for cancer provides no health advantage.
