Substitute for Cat's food

I have a 4 yr old cat, who has had issues with crystals, blood in the urine and UIT's.  The vet put him on Purina Pro Plan Veterinary Diets UR St/Ox Urinary Formula Dry Cat Food, and we have not had any issues since.  However, I am concerned about the quality of the ingredients in the food. 

Dose any one know of another food that would be just as effective, but more natural?

what about feeding all wet, or some wet? there is over-the-counter wet urinary food -- Friskies Special Diet and Purina Pro Plan Urinary Health. 

i would be more concerned with getting more water into him.

Dry foods are pretty counter intuitive to urinary issues - why feed a dry  food when the urinary system needs water to function properly? Cats don't drink enough water from a bowl to meet their needs.

There's info here on diet and urinary issues: http://catinfo.org/?link=urinarytracthealth

Any brand of commercial canned food would work well for urinary issues You could feed a urinary tract specific formula but IMO that's not really necessary. A 100% canned food diet would be most ideal but if you have to, some dry could be fed as long as you limit it to (ideally) no more than half the diet and add extra water to the canned food. I suggest a grain-free dry food.

Prescription foods do come in a canned version (ingredients aren't any  better) so try feeding some of that for now while you figure out commerical brands of food to feed.
