I’m an amateur woodworker… but I KNEW I wanted to build our guinea pigs an epic cage and I didn’t want to be restricted by a C&C cage. I wanted to make adjustments and figure out what worked best for height, style, and ease of cleaning. And I wanted the guinea pigs OFF THE GROUND. Leaning down to clean it is bad for my back.

When I made this, we were using a Midwest guinea pig cage with a rolling base that I built.

So I threw this together with scrap wood while I was in the midst of packing to move last November. Totally logical right? I figured if I needed to move this wood, I might as well move it in the form of a new cage, ha. I was afraid my husband would throw all of the scrap wood away so I attacked a few projects such as this and my dog bowl holder last minute before we moved.

This extra large indoor guinea pig cage is perfect for two guinea pigs, but you could easily expand its size if you needed to fit more than two guinea pigs in it. That’s the beauty of making your own cage.

If you’re new to guinea pigs, make sure to check out my tutorial on how to care for guinea pigs.

Two things to thing about when designing a wood cage:

  • You want it to be easy to clean. Having a cage height that is convenient to clean out is better for your back. I love this idea for a cage with a trap door for easy cleaning, but I was concerned that the trap door may be unsafe for them and that a younger kiddo might open it and drop a guinea pig through. It didn’t feel safe for our household of kids ranging from 1-7 so I skipped the trap door idea. I also worried that even with the trap door, it would be difficult to get over the top of the cage to sweep all of that into the trap door area. Again, I have younger kids and they help so I need the sides to be short enough for them. This would probably be a really neat setup for adults or teens.
  • Make sure you can get the cage inside your house with the dimensions you build it. If I’d made my legs on this cage any longer, I would have needed to build it in the house. Where we were about to move, I didn’t want to have to take it apart and rebuild AGAIN when we moved.

How to Make the Homemade Cage

This is going to be a realllllly rough description of how I made the cage. There’s a lot of stuff I would do differently next time which I’ll talk about at the end. I’m a better woodworker now than I was back in October/November when I built this… I’ve since done a couple of larger projects like our goat barn and our front porch chairs so I’ve got more experience that I’d apply.

We ended up making an outdoor hutch and run when we moved which I’ll be posting about soon… but eventually I’ll remake this with a slightly better woodworking structure. I’ll try to update as that happens! We’re keeping both an outdoor cage and an indoor cage so that we can move the guinea pigs indoors if needed for very cold weather.

Supplies

Tutorial

We started with the rolling base that I built for our Midwest cage. I could have started something from scratch- and probably should have- but I was trying to be quick.

Base for the cage made from plywood.

We cut the sides out for the cage. I made sure to make the sides high enough that the guinea pigs couldn’t get out. I decided to do taller sides for the back and short sides with a shorter side for the front of the cage.

This was just some thin plywood.

Cutting sides out for the cage.

We used scrap 2x4s to give us something to attach the walls to.

This is one of those things I’d fix for next time – it would be more ideal to have the interior be a full rectangle so you could line it with corrugated plastic. You also don’t want the guinea pigs to be able to chew on the wood and wood that sticks out gives them that opportunity.

Added 2x4s to give me something to attach the plywood to.

I added legs… I wanted it tall enough that cleaning wouldn’t be hard on my back.

Now that we’ve had it this height, I’ll say that it was perfect for kids to get their guinea pigs in and out of the cage. Downfall is that it was PERFECT for the kids to get their guinea pigs in and out of the cage. My 1.5 year old crawled in there so many times.

Added legs to increase height of the cage.

I cut a piece of scrap wood to create a hidey nook for them. Sanded down the edges.

Scrap wood cut to create a hay area.

Here’s the initial setup… This area was big enough for the guinea pigs to fit through and I would stuff hay in there (it looks thin in this picture so I may have bumped it out further at some point).

Downfall: This was extremely hard to clean out. They loved the area though.

Hay area pictured from above. Enough room for the guinea pigs to squeeze back there.

I wanted to add a second level. They could easily get on and off this without a ramp. Honestly… I wouldn’t do this again like this. The kids thought it was the best. But the reality is that it’s another wood thing for the guinea pigs to chew on, I attempted to put a rail and it looked awful, and overall it didn’t get a lot of use.

Instead I’d probably try to plan ahead better for adding a more extensive second level. This just didn’t add enough square footage to make it worth the effort and loss of space/cleaning ease below.

Second level to the cage... not a huge fan of this. I would do it different next time.

Note that I used stick on tiles for the bottom of the cage. This did a good job of protecting the floor, but I’ll do corrugated plastic next time to protect the wood. It’s just cheaper and easier.

Here’s the cage empty without the liners in.

I made some fleece cage liners to fit this cage to make cleaning easier.

Thoughts on this Cage Design

I’m pretty happy with how this came out, but I have a few thoughts and adjustments I will try to make in the future.

Problem 1: There’s too many gaps.

Next time I’ll use food grade silicone caulk for gaps and make sure that there aren’t so many structural gaps between pieces of wood. This was just #amateurwoodworkingproblems. I wince looking back at this.

Also the pee leaks through those cracks and in areas where the liners can’t go right up against the wall, there’s a lot of opportunity for leaking.

Problem 2: Too short

The current height is just the right size for my 16 month old and dog to hover over the front side. It’s not ideal. It’s also a bit shorter than I’d like for me to conveniently clean it. It is, however, a great height if you want to sit on the floor and watch them as it puts them on eye level. And if they happen to fall from that height, it’s not as bad as if the cage was up high.

Also in regard to height, I wish I could fit my supplies under this better. A taller design would allow for that. I really want to be able to fit my litter box under it. 

Problem 3: Attractiveness

Next time I’ll stick with one consistent paint or stain color… or just skip it altogether. And honestly, the wood isn’t safe for guinea pigs to chew with or without paint… but it’s probably a lot better without.

Problem 4: Accessibility to Wood to Chew

I have heard so many people say NOT to use wood for cages because most wood will be toxic to guinea pigs WHEN (not if) they chew it. Honestly, our guinea pigs didn’t chew the wood. But I think I’d design this differently to prevent wood chewing next time.

To do this, I would leave most wood pieces on the exterior of the plywood sides so the inside would have just a rectangular flat cage area. Inside that cage area, I’d cut some corrugated plastic to line the cage. This would be a cheaper and easier alternative to the stick on vinyl that I used.

And I’d skip the “accessory” items made from wood. I might decide to make those accessories from fleece instead, however.

Problem 5: Mess

I LOVED the hay area… I have NO idea why I put the hay area on the short end though. The hay falls over the edge. It would have been better to put it on the side with the top level, keeping the front of it lower that the high back. Then the top level could be place on top of the hay section for additional support.

Ideally I’d redesign this to just prevent as much hay and bedding from escaping the cage.

When we moved the guinea pigs to their outdoor hutch/cage, I ended up pulling out the second level, caulking the gaps, and sprucing it up a bit, but I really just need to completely redo the project.

These are fun to build though and experiment with. I’m always on the look out for the perfect animal structures for all of my pets because I like to make my cleaning and care for them easier.
