Whoa -- easy on the catnip, bro.
This is the Super Mario piranha plant cat tree made by Instructables user Geckoo_Designs. It's not like, a super PRO quality Super Mario piranha cat tree, but it's decent. Definitely better than you or I could do. Now I know you hate it when I speak for you, but my voice is way more soothing. I've got this this deep booming man-voice. If life were a school play I would definitely be cast as the voice of God. ADAM AND EVE -- PUT SOME CLOTHES ON AND WEAR THEM IN SHAME, YOU'RE OUT OF THE GARDEN. Greg and Katie -- get naked, you're my new pet project.
Thanks to PYY, who agrees the best cat trees aren't even trees at all -- they're shrubs. Okay that sounded way better in my head.
