Cat question for experienced cat people?

Use more than 1 box...Also use a good neutralizer to get the smell out of the carpet..including once it dries to cut a plastic rug and put it in front of the box..if he goes, then you can just wipe up with some cleaner and be on your way. Is he fixed??????? That helps..He could have a UTI, cats, can't let you know they are sick..so they do this stuff...GOOD LUCK!!!!!!!!
