Mine seems to want to scratch and meow and get rambunctious just about the time i want to go to sleep so here is something you can make to wear that pussy cat out. It was designed to be cut out on a cnc and includes a dxf to cut the parts out that snap together with puzzle joints.

The only thing i thought might be better is if you kerf the backside of the plywood to make it more bendable.
