Out Door Scratching Posts ????

hi i'm from the UK , and wanted to know if anyone has some good sites on outdoor posts ! I have bought plenty of indoor posts from zooplus a site from Germany and they are great but i want some for the garden as my cats now go out in it !!! I have made an overhang and they are so enjoying themselves outside !! But i am not content with just the garden i want fun things for them to climb !!!!!!!
Having trouble finding any !

Actually, some of those posts would look good indoors!

I have a couple of tree branches laying near the house and cat house for my crew to scratch on. Didn't coast a thing.
