Ahhh, Ferret cages usually have vertical sided wires. Not good for an arboreal climbing lizard.
It depends on where you live climate wise as to which outways the other.
Corucia zebrata Enclosure Types-Pros and Cons
Wooden Framed Hardware Cloth Enclosures
Advantages:
Greater surface area for climbing and moving about
Natural UV access
Accessibility for natural rain showers to stimulate breeding and birthing
Better attachment for artifical plants and accessories
Better air circulation to avoid stagnant air
Less chance for infestation by parasites and cockroaches (less dark hiding places)
Disadvantages:
In cooler weather, maintaining a high constant temperature
In dryer, weather, maintaining a higher humidity (75-85%)
If not properly fastened (rare) Getting toenails caught
Direct access to unwanted odors (Cigarette smoke, household cleaners, pesticides, etc.)
Sealed Enclosures (wood or Melamine) 0r Glass Terrariums
Advantages:
Less variance of temperature in cooler climates
Less variance of humidity in Dryer climates
Less contact with adverse odors ie. cigarette smoke, pesticides, household cleaners, etc.
Disadvantages:
Depending on design, stagnant air due to lack of air circulation can lead to mold spores and Other fungal infestation leading to such nasty things as Aspergillosis
More difficulty in attaching artifical plants and accessories
Nooks and crannies can harbor unwanted pests
Lack of natural UV
Lack of natural rain access
Less surface area for climbing and moving about
It is probably best to consider a marriage of both designs. Using a hardware cloth siding for better weather and attaching screw in plexiglass panels in cooler, dryer weather. Remember!
Always leave at least one side or the top open to avoid stagnant air. Remember in your design to have your enclosure designed with a much greater vertical component than length and width.
Regardless of the type chosen, it is recommended to use instead of casters, bakery carts. They are made of tough, thick plastic and have industrial strength wheels that won't knock off like casters. Placing one's enclosure on them works best when one needs to move their enclosure about.
Best of luck with whatever design you choose.
