Water Leak Problem

I am having problems with a water leak problem in my car. Both the passenger and driver side floors are wet constantly because of the cold weather (snow, wet rain). This causes my windows the freeze up on the inside of my car overnight because the moisture that is in the air due to the wet floor panels freezes up. Believe it or not I've been using cat litter to solve the problem temorarily. It helps to absorb the moisture and lately I've had no condensation on the inside of my windows. I have no idea where to start to find the problem/ leak. Does anybody have any suggestions?

yes, its a very common problem. Had to fix mine also. Do a search of the forums, Im sure you will find what your looking for.
