Not only did I switch my 3 cats to canned food instead of dry, but I also mix water into it before feeding to make it even wetter. They like their 'stew' just fine.
I can vouch for the fact that the urine 'patties' that I 'harvest' from the cat boxes are literally twice as much as when they ate only dry food. My cats seem to do much better on wet canned food. We used to have lots of serious kitty kidney problems before, and even lost one kitty to it at 7 years old. Almost lost Pearl too a few years ago, when she was 5. That all occurred when they were on dry food.
