My son sent me this for Mikki as his kitty loves his...he ended up getting a much bigger one since his cat spends so much time trying to lay on it I may too!
Mogli loves those corrugated cardboard scratchers to sharpen his claws, chew on and take naps on. He's currently got 4 of them, though his favorite is on the verge of disintegrating.
I have the same one and one of my cats has been sleeping on it for years. After he wore off most of the cardboard, I covered it with a piece of soft flannel. He sleeps on it daily!
