It does catch the loose litter from the box when the others come out of that box so it IS very good for that also. I use those big people pads I get at Sams Club, that big box of 120 pads for around $26 and I cut those in half to put UNDER to soak up the urine.. Both halves are in there but I find Amy only uses 1/2 of the pad and never both so that saves on replacing the entire pad for only the 1/2 that has been used. Learning as I go.
