There are two products on this website that may suit your purposes instead of the Mess Catcher™.

There is the rigid plastic Marraco Cage Skirt that comes with several side panels, four corner pieces and connectors.  Obviously some assembly is required, but it is a pretty good "permanent" solution to the problem of the mess around the cage.  It comes in sizes to fit just about any cage out there.  Assembly instructions are included in the package.

The second item is made of corrugated plastic (the stuff used in making temporary signs), comes with four side pieces that you cut to size, and four corner connectors.  A quick, less permanent solution.  Click here for details.
