[BlindHandyMan] putting together a cat tree

[Rita]

Cat trees are very expensive.  I am wondering if a lumber yard would be 
willing to cut a variety of shapes from some kind of wood and I could 
cover them with scraps of carpet.  Or would this be a complex project. 
Any advice?
Thanks for any tips to do this and keep it simple.  I could get some help, 
but not much.  Rita
