Looking for cat tree plans...

Hi guys! DH and I are thinking of building the girls a nice big cat tree soon. We keep drooling over them in the store and not getting one. Soooo I was wondering if anyone had any advice?

I've heard that you can find some free plans online too. I did find some so far, but if you have gotten plans online (free or not) where did you get them and how did you like them? Thanks in advance!

TCS has a CD that we will send out that tells you step-by-step how to build a cat condo. All you pay is shipping. I believe I have a few left

Hissy,
If you do have a spare one I would really like to get one. Can you you let me know if you have a spare one. If you do have one to spare also LMK how to pay you for the shipping hubby has said he will build one but we need a plan on how to.
Thanks

Looks like I have three left. If you are interested pm or email me through the site. First come first serve.
