Review on Pet Products Mount Scratcher Kitty by Constance Rodriguez

I have two young (10 month old) cats so I have this perch and also a two tier fluffy fabric, one for two adjacent windows. Each has their own external bird feeder, so the setup is as fair as it gets in terms of rivalry between them. Both strongly prefer this. They don't scratch the surface - they just like hard cardboard. They will take turns doing this or do their best to squeeze through at the same time. The latter is currently barely working with two teenagers, so I'll probably give up and get a second one soon. So far no functional issues with either type but as the down gets older and heavier the suction cups seem very strong and heavy compared to a two story. Recommended!
