If he is a tomcat, one of the best ways to control inappropriate urination is by having him neutered. Tomcats love to urinate all over everything as much as possible as a means of marking their territory. This sort of behavior usually ceases once the hormones are eliminated. Other things you can try is switching up the litter box or the type of litter, adding additional boxes, changing the amount of litter used, or any other variable thereof. Hope this helps.
