My cat is required to eat urinary tract control food. Is it okay to feed him regular canned cat food as long as I add water to it?

Regular food is much less effective in preventing recurrent urinary tract issues in cats which are very prone to repeat episodes - it is impossible to say how sensitive he is and without trying you will not know but there is a chance he could relapse on ordinary canned food. Urinary diets tend to be adjusted to maintain urine pH to prevent crystals and are restricted in minerals and use only high quality protein sources to minimise the risk of urinary tract issues as well as providing an important source of fluids compared to dry food. The very best option in affected cats is urinary canned food but in many cases a high quality, commercial canned food is sufficient - if he relapses on this you will have to source the urinary prescription food as a treatment and prevention

    Moisture content or water intake is more important than brand, although you do want to stay away from discount or store brands. Choose a quality canned food since they are 75% or more moisture. If your cat eats dry, soak it in water before feeding. A grain-free diet is best since cats don't "need" carbohydrates. You can also feed a raw diet. There are several commercial diets available. Again, add water if necessary. Always monitor your cat for straining to urinate or bloody urine though and see a vet promptly if you notice either.

    If she is eating the prescription canned diet, that's fine. It is probably better since it has significantly more moisture than the prescription dry food. You can try feeding just the canned diet or mix in a bit of warm water with the prescription dry.

    The biggest difference between kidney diets and lower urinary diets is usually that kidneys have difficulty with extra protein, and so these diets are usually lower in protein, as well as a few other changes. Lower urinary diets will sometimes alter the urine pH to avoid formation of certain stones. I would recommend that you stick with the food that was recommended by your vet. If you repost a new questions with the exact brand and names of both of the foods, we may be able to compare more information, if you need it.
