humans loved it, cats hated it!
very economical to use, easy to dispose of, good odour control - just one problem, 2 bengals who refused to use it!
they used it at first then gradually started using other areas of the house instead, completely unknown to us at the time & such a treat to find out at a much later stage when we were ripping up carpets as having work done. cats!, you've gotta love 'em!
