Review on Van Ness Trackless Litter Mat: Assorted Colors, Size 13 3/4'' x 17'' x 5/8'' - Keep Your Home Clean and Tidy! by Christine Wilkie

Catch some kitty litter, but not much. Worked well when my kitten was a few months old, but as he got older he became too small to catch most of the debris he pursues, even with the box's high side lid. Maybe my cat is just dirtier than others, but for me she catches about 20% of her litter. It catches litter, but unless you have a little kitty, this mat doesn't help much with tracking.
