Kitty Kornhole Cardboard Refills are availalble in two sizes: 5" and 10", as well as a semicircle section option.
 
Cats shred small portions of scratching pads before you have to throw them away; however, with Kitty Kornhole, you can easily recycle the worn areas by unbolting the top and replacing them with our pre-cut cardboard refills.
 
Depending on supply, up to 100% of the cardbaord used to make Kitty Kornhole is post-consumer recycled material. Some of this recycled cardboard is sourced from pet industry partners, like Mud Bay, a respectable local pet supply store chain.
