Oh, super! I’ve got a set of the ones you linked to, and boy are they pricey, considering it’s cardboard. Sadly, the cats don’t really have anything to do with them, I don’t know why. On the other hand, they adore the wedge-shaped one I made for them a couple years ago. To the point that I’m going to have to replace the surface scratchers, they’re totally in shreds. Let us know how your kitties like the Tetris ones!
