For litter tracking, I bought one of those black floor mats that are meant to be used by doors leading in/outside of the house...its the kind that looks like it has a bunch of little black "wires" criss-crossing all over...kinda squishy/sinks in a bit when you step on it. The litter falls right to he bottom of the mat when my 2 cats step out of the boxes and onto the mat! I have 2 door mats right outside of their boxes (2 boxes, sitting right next to each other practically)...these mats have little squarish indents (pattern) that trap a little bi of he immediate "I just stepped out of the litterbox" pellets. Then, right after the end of those mats is the big wirey one I described above. WORKS LIKE A CHARM!! There is literally MAYBE a few specks of cat litter here and there right outside of the mat, but NoNE through my house anymore!! Hooray!
