I built these in woodshop class about 2 years ago. theyre 1.5 ft tall, 2 ft deep, and 4 feet long. I kept a tiger retic in one and a burmxretic hybrid in the other. They have a full plexiglass window in the front which opens up to get them out. And a small door on top which I used to feed them through. They have a hole on each side of the top with screens, for lamps to sit on. They are painted white. Im not a professional carpenter but they worked for me and hey theyre free. They have handles and hinges. Pick up in Northwest Ohio, Lima to be exact. Email me if you want them
