Can anybody help me train my cat?

Filed in - Advise Welcomed

I have a cat, a persian. His name is Lord Beezly (i know very nerdy). My family has had him for about 5 or 6 years and for a while now he's been urinating on clothes and other things that are left on the floor. Obviously, this habit is very annoying. I'm not sure how to steer him from this. The only thing I've really tried is using cat attracting litter, but it doesn't seem to work. It also seems to be getting more frequent as time goes on. I really don't know what to do and I'm afraid we might have to get rid of him if we can't figure out anything to do. Please help! Thank You!
