Our humans apparently spent a few weekends based on a plan in their head. We know they had the benefit of some old trusses from a mobile home they had just demolished, which keeps the rain off us quite nicely. The wheels have an old Toyota jack attached so they can jack up one end to move it around and take us to fresh ground. We think they did quite a good job constructing our house.What we would change: It would be nicer if our humans could make it lighter to wheel about, we do especially like the window so we can look out on a rainy day. We are afraid to ask what this cost in materials and time, but we’re worth it!
