I have free roams, and wished to have litter boxes that matched my decor
and flooring..  Never thought I would find it until I found this site.
Rather pricy for a poopy pan...

But cats and ferrets immediately used the boxes, and the rugs have rubber
backing and pick up the extra litter that gets on little paws.
