Hahahaha! No, it's a place for them to climb and such. My husband and I had been talking about using a castle idea to build a place for them to climb and recline and such... I'd suggested using a flat board against the wall with key areas in 3D, plus bridges and such. When I was searching for Bowser Castle images so I could sketch out the idea, your image was the first one on my image search and it was the one that we both really liked. Not wanting to just take your art and re-imagine it without your permission, I thought I'd ask. This is for our cats, in our home. I would take pictures and post them, giving you full credit for the base design of the castle (which would be re-rendered by me in a much less awesome version) for the 2D image on the wall. I haven't seen anything online like what I'm talking about doing, so I can't really show you pictures, but, I hope I've described it well enough....
