I have gone through numerous cat posts over the years — replacing straggly carpet with hemp rope and/or carpet pieces until I was sick of carpet stubble. After an extraneous search in a variety of venues for a cat perch that would satisfy the cats and not look too hideous in my living room, I finally found an artsy looking perch that will mix and match with my moves for years to come! The attached tree was discovered at Muttropolis (www.muttrupolis.com). The girls are happy and it blends nicely with my bamboo floors!
The side of this post has a replaceable sisal carpet. There are also sisal panels on each level and one inside the house. The house roof has a foam pillow and the roof itself lifts off for easy cleaning.
