I have different types of scratching surfaces. I have a Natural Scratch made of cedar, that Diamond and Smokey like. I have a 4 foot high sisal post that a lot of the cats like. Bosun loves the horizontal cardboard pads, especially spiked with fresh catnip. Tictac likes wood from outdoors.

Fortunately, a lot of these can be made for a lot less than what they cost to buy. Someone on a cat site, I forget where, had a whole LADDER covered in sisal! Ambitious or what?

Good luck!
