i am wondering if anyone has or is using this brand " Simply Nourish" . I was using EVO grain free but the cat with digestive issues did not like it and it's so expensive. My cats are , 8yrs old , and a 4. Month kitten. They are all boys and I heard that the EVO has a lot ( too much ) of protein that can cause kidney issues to male cats , it's 50% protein and Simply Nourish is 36% . Love to know if anyone is familiar with this SN.
