Construction How do I fix a hedgehog enclosure that keeps getting too humid

[smeelytop]

Hey folks! So I’m kinda losing my mind over my hedgie’s setup lately. No matter what I do, the enclosure keeps getting super humid and it’s starting to smell funky. I clean it, switch bedding, crack the window, the whole nine yards… but it still ends up damp and I’m worried it’s gonna mess with my little dude’s health. I’m starting to feel like I’m doing something wrong even though I’m trying so hard. Has anyone dealt with this before? Any tips, hacks, gear recs… literally anything would help. I just want my spiky potato to be comfy again.

More ventilation, I think.

Any small fan in a window will help.

I bought a small window fan for my shed and just framed it in. Pretty straightforward.

Clean its poop bed every day.
Could be the reason its smelling funky.
And lots of bedding.

By the way, do you have a hygrometer in there, to ensure you are tracking the actual humidity? They're about 10 bucks.

Allow cooler air to enter the enclosure low down, slowly, as it warms and takes up excessive moisture, its density will fall, so it will rise to the top, where you will extract it, or allow it to vent.

What are keeping it in?
aquarium (not much air circulation)
bird cage (lots of air circulation)

Something like an aquarium will retaining exhaled moisture or moisture from other sources.

Google recommends a solid floor for their feet and 2 x 3 feet of space.

Could you please describe that enclosure?
The animal breathing is a source of humidity.
Exhaled warm air eventually cools down and becomes unable to hold some of that moisture, which then becomes condensation.
That exhaled humid air needs to be exhausted from the enclosure and replaced with dryer fresh air, which will be able to absorb some of that condensation.

And there is no way to help without any information about the enclosure itself.

And there is no way to help without any information about the enclosure itself.

A small leak could account for a big increase in humidity. How much water does Hedgie drink? Is it outside with a dirt floor? etc. etc. so many possible variables.

Over humid conditions could harm the little person. Needs a solution soon, I think.

Just a thought but what about those hygroscopic crystals included in shipments that have to stay dry? Their precise name eludes me.

EDIT: I know Wiki is frowned upon in the serious parts of the forums but it's a broader topic than I expected:

Hygroscopy.

Silica gel ($\text{Si}\text{O}_2)?$

 

[sbrothy]

Yeah, I think that's what I was thinking about. Probably inadequate for the job though.

These kinds of things will become saturated and stop absorbing humidity.

 

[sbrothy]

Yeah, upon posting it it almost instantly dawned upon me that it wasn't a viable solution over time.

But it is a short term fix if you buy the silica gel in bulk, as crystal cat litter from a supermarket. You can revive the crystals in an oven, or microwave them in a glass or ceramic dish.

Do hedgehogs eat rice?

 

[DaveE]

Their precise name eludes me.

Drierite is what you'll find in the optics labs, where some crystals HAVE to be kept dry. It has an indicator (color change) so you know when to change it. Is it OK for Hedgehogs? Should be OK if they aren't eating it. OTOH, it might be a PITA to keep changing it when a fan could fix the problem. IDK.

[DaveC426913]

The idea of artificially dehumidifying the enclosure seems misguided. Fix the problem at its source: increase ventilation to replace humid air with dry.

While I know it's a myth I couldn't avoid envisioning exploding hedgehogs. It'd basically be a nail bomb!
