Cage Building Materials
The following is a detailed review of the materials that can be used when building a DIY cage, or when providing shelving in a commercial cage. There is also guidance on the use and fixing of shelf edging materials.
Edging techniques
Some shelving materials are only safe when suitably edge protected with kiln dried pine. When edging shelves, it is important to choose an edge fixing that provides suitable protection. Face fixing the edging minimises the risk of degus being able to bite at the shelving material. Edging which is fixed from underneath leaves the edge of the shelf exposed to biting and with some shelving materials this can expose the degus to potentially harmful chemicals, unless an alternative method of edge protection is used, such as galvanised thin coat angle bead.
Edging materials
General planed softwood for indoor use in DIY stores is likely to be kiln dried pine, it is only rough sawn timber or some other mouldings which may be a different type of timber (hardwoods, tanalised timber etc). Rough sawn timber is discouraged mainly due to the fact that it will have a high moisture content and as a result could contain fungus/mould which could be harmful to degus, and may still contain harmful volatile compounds from the sap if not kiln dried. Some hardwoods can create harmful dusts that can create breathing difficulties, also timbers that are tanalised may be unsafe due to chemicals added.
Shelving/flooring materials
Notes -
1. Some of the above materials can be purchased in non-toxic format, but it should be assumed that formaldehyde is present and the material is toxic unless specifically stated by the supplier.
2. Should ideally be 12mm thick or sagging is likely to occur, for spans in excess of 600mm plywood of 15mm or 18mm thickness may be more suitable.

Kiln dried pine or Aspen | CLS(Canadian lumber size) | Tanalised timber | Hardwood |
General planed softwood (also known as planed redwood). Commonly used for floorboards, tongue and groove cladding, timber architraves/skirting boards. | Fast growing pine, usually identified by its rounded edges comes in limited sizes (50 x75mm size is ideal). | Pressure treated timber usually has a green/brown appearance for external use (decking, tiling lath etc). | Used for feature timber/mouldings. Oak, aspen, fruit woods may be available and are safe. |
Suitable for all areas in a degu cage, safe for gnawing. | Very cheap compared to standard kiln dried pine. Safe for gnawing | Most treatments contain toxins, but some treatments for cage/hutch building are safe. Assume these products are UNSAFE unless clearly indicated as pet safe | Multiple varieties from various trees, many are listed in the safe tree/wood list on the forum. However certain species can be unsuitable for degus and can produce dusts that can affect breathing. |
Shelving/flooring materials
Material > | Chipboard | Laminated chipboard | Medium density fibreboard | Blockboard | Plywood (2) | Oriented strand board | Laminate flooring | Timberboard | Matchboard/T&G floorboard |
Also known as> | Particle board | Melamine, conti-board, furniture board | MDF | OSB, sterling board, aspenite | Tongue and groove cladding/traditional floor board | ||||
Description> | Chipboard is made by mixing recycled wood particles and paper particles with chemicals to form a slurry, which when heated and compressed forms chipboard. The result is a rigid board with a relatively smooth surface | Chipboard that has been finished with a surface veneer | A sheet board creating by compressing wood fibres that are mixed with wax and resin. A much denser sheet material that is generally stronger than chipboard. | A sheet board creating by sandwiching softwood strips between two sheets of veneer (plywood) | A sheet board creating by sandwiching layers of veneer (thin sheets of wood together) | A sheet board creating by compressing layers of wood flakes together | Laminate faced chipboard or laminate faced MDF in strips or squares used as a flooring material | Timber sheet material made by joining softwood strips along their length (laminated timber) | Timber with a groove cut along one edge, and a tongue machined on the other that slot together to form a cladding/flooring material. |

Toxic> | If eaten (1) | If eaten (1) | If eaten (1) | If eaten (1) | If eaten (1) | If eaten (1) | If eaten (1) | If joints exposed (1) | No |
Moisture/ urine resistant> | Not as standard although water resistant versions can be obtained (usually green in colour) | Yes, except on edges without veneer | Not as standard although moisture resistant versions can be obtained (usually green in colour) | Partially, although urine will be absorbed and is likely to stain and create smells. | Partially, although urine will be absorbed and is likely to stain and create smells. | Partially, although urine will be absorbed and is likely to stain and create smells, uneven surface is also difficult to clean | Yes, except on edges without veneer, although moisture resistant versions can be obtained (usually green in colour) | Yes, although urine will be absorbed and is likely to stain and create smells. | Yes, although urine will be absorbed and is likely to stain and create smells. |
Degradation> | Will degrade quickly if exposed to moisture, by absorbing moisture and swelling (unless moisture resistant version used) | Will degrade quickly if edges without veneer are exposed to moisture, by absorbing moisture and swelling. | Degrades quickly when wet by absorbing moisture and swelling | Will degrade eventually through exposure to moisture, but WBP (weather & boil proof)versions will last for years even if located outside | Will degrade eventually through exposure to moisture, but WBP (weather & boil proof)versions will last for years even if located outside | Will degrade eventually through exposure to moisture. | Will degrade eventually through exposure to moisture (unless moisture resistant version used) | Will not generally degrade through exposure to moisture unless for prolonged periods | Will not generally degrade through exposure to moisture unless for prolonged periods |
Suitable as un-edged shelving/ flooring> | No, unless no edges are exposed | No, unless no edges are exposed | No, unless no edges are exposed | No, unless no edges are exposed | No, unless no edges are exposed | No | No, unless no edges are exposed | Yes | Yes |
Suitable as edged shelving> | No, unless moisture resistant | Yes | No, unless moisture resistant | Yes, but urine may stain/smell | Yes, but urine may stain/smell | No | Yes, but joints may be prone to nibbling | Yes | Yes |
