Arrived really quickly. The size is accurate, materiaal looks good, top layer with holes is it is approximately 7 mm think, and looks strong, is a kind of EVA material, pleasant to the touch, not to soft, not real hard. Almost no smell. I put the mat in the doorway to test if the cat would walk over it, and he did without problem. I have it under/in front of the litterbox, but the cat hasn't used the litterbox yet.
