Natural sisal is what cats actually want to shred - coarser than carpet and it does not fray into loose threads, with each mat edge-banded so the surface stays attached. A latex backing keeps the mat still on a wooden floor, and adhesive hook-and-loop tape lets the same pad go on a wall, a sofa side or a door instead. Each measures 24 x 16 in and the six together weigh 5.5 lbs. They lie flat, so nothing needs assembling. Natural fiber tone that disappears against most flooring.
