I am Nathan, I'm 11 years old and literally build the scratchmaster units by myself. My dad (Yoshi) cuts the wood frame pieces for me, he also built this website- but everything else is my own.
I make these because I love cats, and I found that most cat toys and scratchers are made of plastic and just don't last. We already have too much plastic in our landfills. This, and the cardboard that I use is material that is diverted (re-use is better than recycling).
