A lot of folks have stated that galvanized wire can cause UTI's due to the fact that gliders urinate on the metal and the metal reacts with the urine. Over many discussions, I have seen it come down to the fact that the metal breaks down much quicker than if you were using a powder coated cage. As the metal breaks down, it collects bacteria from the urine and as gliders mark their territory along the cage, the bacteria then collects on the body and can cause problems. So it's not that the metal itself is toxic as many have stated over the years (since it is zinc plated - gliders do not ingest the metal), it's more along the lines of bacteria collecting on the grids. You can't clean the metal and well as you could a powder coated cage. Powder coating does not allow for the growth of bacteria as much as the galvanized wire. Some folks say that it's ok to use it if you replace it often, but I just wouldn't waste the time with it. Have you considered investing in a reptarium?
