I have multiple cats and they love to scratch our upholstered & leather furniture, despite having several sisal scratch floor pads lying around the house.  I resorted to purchasing this vertical 3 sided scratcher as an attempt to save my furniture!  The cats were initially quite curious but now only one of them uses it regularly, as he prefers to stretch and scratch 'vertically'.  The other 2 prefer scratching existing horizontal floor pads.   After 1.5 months of use, the cardboard is holding up quite well, despite some loose pieces coming off - which is expected. With 3 sides, I expect it to last for at least a year or more (TBD).
