Thanks for the response.
That's what I was thinking but I haven't ever used a PVC/plastic cage for long term keeping and in addition to the previous poster's comment it made me wonder. I am looking into getting these for 2 GTP, 4 Balls, and possibly some crested geckos.
These would make some beautiful display cages in my opinion and add the fact that they are stack-able and it makes for a great place to show off some beautiful animals!
