My cat loves this board she went crazy for the cat nip sample that came with it, they send a card with it that says if you send a video of your cat enjoying the scratcher the company will send you a free re fill board , I haven’t gotten around to it yet though. I did think the bases was going to be real wood or particle Board… i didn’t read and just looked at the picture…but it’s cardboard with an outer layer made to mimic wood
