Materials for Making Snake Cages
What kind of materials should you use when constructing a snake
cage? This question was posed to me once by someone wishing to
build their own snake cage. They were particularly asking about
pine and cedar as they had heard these were no good. But it did
raise the question about what are the best materials.
All-glass, tubs, melamine cages, screen cages, there are many
different types of housing systems for herps. Take your pick,
depending on the adult size of the animal, how much room you
have to spare, and how much money you are willing to spend!
Aquarium tanks: Good choice for keeping snakes under 6 feet
requiring a swimming pool or humidity. If a screen top is used,
there will be enough ventilation to keep a sand boa or leopard
gecko or any desert animal in it. If higher humidity is needed,
the screen top can be partially wrapped with Saran wrap, and the
tank can be treated as a tropical garden; put soil in it and
plant some plants to raise the humidity! Viewing is
unrestricted, the tank can be easily cleaned, it will not get
scratched, and temperatures are easier to maintain. They are
very cumbersome to move around, especially big ones, or
fully-loaded ones. They need to be on a solid table or stand and
if you do want to move them, the stand will need solid castors.
Plastic/Rubbermaid tubs: The feeding trough sizes are great for
turtles! You can half-fill them with water, pile rocks in a
corner for the basking area, put a lilypad or two in it, and
have your own indoor pond complete with turtles! For the more
common sizes, the sweater boxes and shoe boxes, any non-aquatic
herp can be kept in them. In fact, these are used in breeding
racks and in households with too many herps to be able to have
the amount of tanks/cages to keep them all in. Not good for
arboreals, as they cannot climb. Perfect for use during the
quarantine period prior to introducing a new animal to an
established collection. These restrict viewing, and are
generally limited to hatchling animals. Good to use as an
emergency/isolation enclosure.
Melamine cages: Melamine is the stuff many countertops are made
of. They resist moisture well, so rotting is usually not a
problem. They're easily cleaned as well. Custom-made enclosures
are sometimes made of melamine, and you can build
furniture-quality enclosures yourself. These can be made to fit
a leopard gecko or a fully grown green iguana. With a glass
front, these enclosures hold humidity incredibly well.
Wood [plywood] cages: Same as for melamine, except MUCH cheaper
and easier to work with. Both enclosures, if ordered from a
custom builder, can cost a great deal depending on size and
material.
Screen cages/Reptariums: Excellent for anoles, chameleons,
light-bodied snakes, and young water dragons. The major
disadvantages are that the largest size is only 29" x 29" x 72",
humidity is very difficult to keep up, and strong animals could
knock them over or even move them. This is a great idea for an
easily-transported cage for small animals.
MDF or craftwood: Same as for Melamine but also much cheaper.
Good for use in combination cages ie Melamine base with MDF
sides, back etc. It can be painted, has good thermal properties
and if used in conjunction with a coating material such as
Contact, will hold humidity well. Excellent to work with and has
a smooth finish. You can also use thinner sheets as it retains
its rigidity. Some people recommend wearing a mask when cutting
or routing MDF as it can be dusty.
Pine or Cedar: Neither of these timbers should be used to
construct a cage. Making the whole snake cage from the pine or
cedar has potential health problems for the animals. These woods
emit aromatic hydrocarbons that can damage the health of the
animals and cause various symptoms. There is probably little
issue using as the woods in framing, as the wood has often dried
out a lot and released much of the volatile material, or at the
very least, the rate at which it is released is very slow.
It also is recommended that you do not use pine or cedar as a
substrate. Pine and cedar wood shavings used as substrates have
a very high surface area and so the hydrocarbons are released
much more readily, making them potentially toxic, especially as
the animals like to burrow and immerse themselves in their
substrate material.
PVC Tubing & Mesh or Plexiglas: These materials make excellent
larger cages for animals such as monitors, larger snakes,
chameleons and iguanas. They do tend to lose a bit of heat but
any large enclosure will require some effort to maintain a
higher temperature. Lighting at the top and some at the sides
(if needed) will create a sufficient heat gradient. Short of
building a large frame with glass and a large door, this is the
most economical way to make a larger enclosure if you do not
have woodworking tools.
Overall, if you want to construct your own cages for most
snakes, you are probably better off using plywoods, melamine and
MDF types of materials for most of the cage. There does not at
this stage seem to be any identifiable health issues caused by
these materials. Another benefit with these materials is their
insulating properties. Glass is not a good material for most
snake cages (except aquatic species) as it loses heat rapidly.
Many glass terrariums have an open top with no seal and this
also causes a high heat loss. This means the glass cages are
more expensive to heat if you use certain types of heat sources.
The front of the cage can be sliding glass, Plexiglas or a
constructed glass door. A pine, oak or similar timber frame at
the front will give the cage a more professional and decorative
appearance.
If you paint your cage, remember to let it dry out for a minimum
of 2-3 days to release as much of the volatile material from the
paints. 5-7 days would be even better.
It is a good idea to make the base of a wooden snake cage from
melamine and use Silicon to seal around the edges, to prevent
moisture penetrating the melamine or plywood sheeting.
There are hints and tips on applying Silicone in the "How to
Build snake Enclosures" booklet.
A base of vinyl flooring can also be used if you are concerned
about water penetration into the timbers. Be sure to seal it
with Silicon and seal the holes where temperature probes are
passed through.
You can also coat the MDF or plywood interiors of the cage with
'Contact', a plastic sheeting with an adhesive backing, in any
colors you like, before you assemble the cage. This will remove
the need to paint the cage inside, reducing fumes, and also
provide a water proof seal for the MDF or plywood.
Contact comes in a range of colors and is very easy to apply cut
and apply.
There is much to be gained from building your own snake cage. It
is good fun and will give you, as a snake owner, a great deal of
personal satisfaction. Before you do go out and purchase a
snake, take some time to research what is the best sort of cage
for your pet. You should be aware that many snakes will grow
considerably over time and you may have to build a number of
cages.
