Hey Thanks!!! Well I hope you can build a great one so they can be very happy and is not that difficult. I did mine very simple. Didn't go to all the trouble of making the corners perfect. The habbitat is 24"Wx60"Lx12"H. The floor is a 1/2" plywood and the walls are 1/4" plywood. On One side of it I cut the walls to put some acrilic panels so the sunlight can reach the plants and to Dobby. And a few screws to attach the 2X2 baluster to the floor and the walls and your done!! Ahh and all the wood has to be treated so it doesnt get damage with the water.
