Is Plywood A Safe Material To Use For A Chinchillas Cage?

When it comes to building material, plywood is pretty much a jack of all trades.

This affordable manufactured wood can be used for both interior and exterior construction. It can also be used to build cabinets and chairs, furniture and flooring.

So, what’s stopping you from using it to build a home for your chinchillas?

Well, in this article, we reveal what really goes into the manufacture of plywood. You’ll also learn why the glues found inside this engineered wood may also make it unsafe to use around chinchillas.

What Is Plywood Actually Made Of?

Well, plywood is an engineered material, which means that it isn’t a natural wood.

Instead, plywood is made up of multiple thin wooden plies. And those plies are placed atop one another, at alternating angles.

However, the particular wood used to make plywood can vary widely. Various types of wood, from Douglas Fir to Maple to Birch, have been used to make this material.

Still, one thing all plywood sheets have in common, is the fact that an adhesive is used to make them. And when it comes to a typical plywood sheet, that adhesive will contain formaldehyde resins called phenol-formaldehyde.

And Why Is Phenol-Formaldehyde Adhesive So Toxic?

It all boils down to the fact that formaldehyde itself is incredibly dangerous. If it is ingested in large enough amounts, it is poisonous — both to humans and pets.

Even formaldehyde vapor can cause severe respiratory problems. And in liquid form, it can burn our skin.

Does That Mean Plywood Can Release Toxic Fumes?

Solvent-based substances, (such as glues and paint), all go through something called ‘off-gassing’. Off-gassing refers to the fumes released from finishes, glues, and paint, as they dry.

It can take just a few hours for wood glues or paints to dry to the touch. However — as anyone who has painted a room can attest — it can take weeks for the fumes to clear up.

And the same goes for phenol-formaldehyde based glues. It can take up to 24 months for this glue to stop releasing significant amounts of fumes into the air.

Nevertheless, store-bought plywood will have already had time to sit and dry out. Which means that formaldehyde off-gassing shouldn’t be all that severe with this plywood.

But, even if off-gassing isn’t an issue, ingesting any plywood at all can still bring harm to chinchillas. Why? Well because…

…Treated Plywood Is Full Of Chemicals

Plywood is not rot-resistant. So, more often than not, a sheet of plywood will have been ‘treated’ with rot-resisting chemicals.

And these chemicals are anti-fungal wood preservatives. Their job involves fighting off the bacteria responsible for wood rot.

However, the chemicals infused into treated plywood — such as Chromated copper arsenate (CCA) — are toxic. Certainly much too toxic to risk being ingested by chinchillas.

Now, having said all that, you can still find and purchase untreated plywood.

But, without a wood preserving chemical treatment, untreated plywood will rot away fairly quickly. Especially if moisture or humidity gets into it.

Is There A Formaldehyde-Free Plywood I Can Use Instead?

There are certain specialized formaldehyde-free plywoods you can buy. And they are marked as NAF (No Added Formaldehyde) Plywood.

These plywood sheets are glued together using a natural-alternative adhesive, instead of formaldehyde-based glues.

That’s Great! So, I Can Use NAF Plywood Instead, Right?

Not quite.

Sure, NAF Plywood completely does away with toxic wood glues. But, it replaces them with a soy-based adhesive instead.

Which is great news, until you realize that Soy contains something called phytoestrogens. Phytoestrogens are plant-based compounds, but they can cause hormone imbalances in both humans and chinchillas.

So, if your pet likes to chew on wood — and you suspect they may also chew that plywood — then this is another possible safety risk.

Now, maybe this is all acting with an over-abundance of caution. Maybe avoiding even NAF plywood is simply being a little too careful.

But, it’s always better to err on the side of caution, when it comes to pet safety.

So Does That Mean Plywood Is Not Safe For Chinchillas?

Well, the safest type of wood you can use is always going to be untreated natural solid wood. What’s more, that wood must come from a tree species that isn’t harmful to chinchillas.

Which means that plywood is not a wholly chinchilla-safe material.

In fact, you can go one step further and avoid all manufactured woods — since they often contain toxic chemical glues.

To Wrap Up, Here Are The 3 Key Takeaways From This Post…

  • 1). Plywood is a manufactured wood, often made using formaldehyde-based glues.
  • 2). Plywood also tends to be treated with chemical wood preservatives.
  • 3). When it comes to the health of our pets, it’s better to be safe than sorry. So, avoid using plywood altogether.
