They are probably not a good cage for reptiles simply because it would be hard to keep the heat and humidity right.
Perhaps something like button quails/king quails (same bird, name differs depending on your country)? I have kept breeding pairs of my king quails in "rabbit" cages in the past, you just need to consider the door size and how easily the birds scare, I had them inside a building because the doors went the whole length of the cage and I must say that was a wise choice as I did have a quail escape the cage on a couple separate instances and they can fly a surprising distance. A different cage of similar size I had happened to have a smaller door that was about 1/4 the length of a cage so the birds never jumped out of that one.
