I love the midwest critternation cage on amazon, also sold at petsmart
as the all things living cage (1/2 inch barspace one not ferret one). some of my older ones are starting to show signs of rust around the edges, so they dont
also the brisbane, congo, madagascar cages are good, I had one brisbane and it
had good powder coat with no signs of rust when I sold it with a few gliders.
these cages are sold on several websites I think.
