Usually made from storm fallen cedar, though other tree types have been used. I find useful and interesting shaped branches, and assemble them into sturdy cat trees. I've given these away, sold them, kept them for my own cats...all the cats I know love them.
These sell for 900-1,200

Real branch cat tree
This real branch cat tree has flagstone platforms. I also build patios http://www.devineescapes.com/flagstone-patios
The real branch cat tree has no base to support it. Rather, it bolts right to the wall via twi deck screws.
One of my earliest real branch cat trees, pardon the low resolution
