None of our numerous store-bought cat trees were ever large enough for our 16lb boy, so I grabbed an old area rug and plywood scraps I had and took matters into my own hands.
It's about 70% compete, I'm gonna add at least a platform on top of the post, and my partner wanted a cat hammock, so I gotta figure out where/how to incorporate that.
Lemmy know what you think!
I don't know about OP, but when I put rope on my cat-tree's soft-fabric column I just wound it around the column (cylinder, don't know if it would work as well on a squarer support) as tightly as I could and safety pinned the bottom end to the 2nd to last row. The tight coil encourages friction and prevents slippage when he scratches it. The rope hasn't moved, aside from when I rotate it for a fresher side, since I placed it over 2 years ago.
