deonk1,
Was it this picture you were referring to ?...

IF so, that looks like a very interesting idea...
Liquid drops through, solids suspended...ok,
But I do have a suggestion if used...
I'd put a piece of Plastic underneath that device, Hardwood and
Carpet can really be damaged by lingering Urine, and...
I still think that getting whatever type device one might use, placed
near or toward the outside door to the Potty area. That should create
a habit for his animal in going the right direction for that. MY thought
that if you can get them going toward or to the door, going through
it won't be that much a bigger step.
