Science Diet c/d for Cats

I have two cats that are on Science Diet c/d for urinary issues. They have been on it for over two years. How long will they need to remain on this diet or is this a life time diet?

ANSWER

It is often a life-time diet. If they are doing well since going on it, switching to something else would be a gamble and most of us don't want to take that chance. You can try it, but there is no guaranteed outcome.
