I have never fed the cats Royal Canin or Hill's special diets. I was lucky, we only had one blockage and no crystals after that.
One of the dogs got a bladder stone the size of a shooter marble. We went straight to surgery, no we aren't going to buy the fancy food and hope for a month of uncomfortable peeing that a stone that big dissolves. The vet did say she had to eat the Hill's special diet. She refused. She ate acorns and pecans she found in the yard and lost a good bit of weight. So did her companion dog. I said enough and put them back on regular food, which doesn't exist anymore. Neither ever had another stone.
A neighbor believed she was feeding her cat special Hill's kidney diet. When she went on vacation I was chosen to go fight, and I mean fight the food down that cat. No one thought of syringes then just fingers. Grim. later discovered the cat, who was supposed to be floor bound was jumping on the table eating grocery store dry food left up there for the others.
Neighbor's cat lived to be 20.
I think it's genetics, willingness to drink water, and luck.
My cat won't eat wet food. Since I already had one years ago, who starved herself to death (I think she missed her former owner and nothing we or the other cats did helped) I'm not trying to force her to. She's sensitive to chicken as a meat, but can tolerate chicken broth and chicken fat so she eats Fromm.
