Hey Zoo and celtic thanks for stopping by. The cages are 16g 6" hog wire fencing. Usually comes in 150ft and 330ft rolls at your local farm and garden store. Zoo except for minimal leaf trimming so far all the branches are stripped from the cage edge to the stock for air circulation to prevent pm and refresh co2. Cages are 2ft x 4ft sitting on top of 20g botanicare rez and lid.
