Yep. I have made my ratties a cage. It is 4 feet long and 2 feet wide, and 2 feet high. It is mainly for them to play in the grass during the summer months. I don't have the picture loaded on to the laptop, other wise I would post a picture of it- I have posted the pictures before.

As soon as I get the money, I plan building a HUGE cage, as huge as my room will allow me to make it. I think it would be a good summer project for me and my friend to work on.
