I have had my cages for a couple of years. A quick look at his website tells me that he has made a lot of changes. He says that 99% of his customers buy white cages that are FDA safe. He says that the black cages are an entirely different material. Mine are black, are very heavy, and quite well insulated. Evidently the info that I gave you is outdated. He does make well constructed cages and communicate well in my experience.
