This is what we setup for our two RT babies to spend a few hours outdoors each day. It is made the same way as brains enclosure. The bottom is has hardware mesh running all the way across. They will spend a few weeks in this until we finish our patio, then we will do their large enclosure. I don't know the exact size, we made it out of leftovers we had
. Each side is about 30" x 20". It should only be for a few weeks
