Over-the-door cat scratching post
 A removable over-the-door suspending scratching device for cats which is self-dampening and provides a large volume scratching surface without requiring floor space for a base, which encourages a pet to scratch at and climb the device rather than upholstered furniture. A track suspending a raised rolling target may also be formed as part of the scratching device.
