My adult male cat was treated for FLUTD and our vet recommended that I feed him Royal Canin's Feline Urinary SO dry kibble and canned food from here on out. Both of these contain cereal grains.
Before he was treated, I had him on a diet of whatever grain-free kibble was available near me (typically Taste of the Wild or Canidae), supplemented with canned varieties of the same brand.
I would like to return him to a grain-free diet, but I am worried that taking him off of the vet-recommended Royal Canin diet will cause further urinary complications.
Are there any grain-free dietary options I can explore that will reduce the risk of FLUTD as well as (or nearly as well as) the Royal Canin SO diet?
I am open to trying raw meats/offal options so long as they do not pose a risk of exacerbating struvite crystal formation.
