Too many potatoes
My tomcat had oxalate stones and unfortunately has to eat special diet food now. He’s really picky with this food. I add some water to it so he’ll eat it better. Unfortunately, there are a lot of potatoes in it. Even my cat who usually eats anything won’t touch this food. Other brands are even worse. The Diet Urinary food is eaten very happily, but unfortunately it’s only for/against struvite stones.
