Exotic Nutrition's 4-Level Mansion Cage has 100% metal construction (no plastic shelves, ladders or trays), making it chew-proof! This cage is made specifically for housing small mammals like chinchillas, rats, ferrets, degus, rabbits, guinea pigs and more. This cage is manufactured by professionals from the HQ cage company with quality materials and experienced workmanship. It is designed with safety in mind and durability to last the lifetime of your pet. Assembly is quick and easy, view the video below.

  • Bar spacing is the recommended ½ inch wide (2 - 3 mm thick), narrow enough to prevent escape.
  • Entire cage is professionally finished with an animal-safe powder coat for durability.
  • The two solid metal pull-out trays (1.25" deep) catch feces and debris, then can easily slide out to make cleaning a breeze. The trays sit on top of a metal wire grate. Metal flaps on the outside of the cage close over the trays and fasten into place.
  • The cage sits on a stand with four wheels, allowing you to effortlessly move it from room to room. Wheels can be taken off to make it immobile.
  • There is a space-saving accessory shelf below the cage, perfect for storing food, toys and other cage items.
  • Two complimentary plastic double-feed dishes come with this cage.
  • Ramp Covers are available separately - these fleece covers slip over the metal wire ladders for pets who prefer a solid surface.

Cage Dimensions: This cage measures approximately 58" tall (44" off stand) x 32" wide x 20.5" deep. It includes two solid metal floor bases and two solid metal platform shelves (11.5" x 20.5" x 0.75" deep) along with three metal wire ladders (6" wide x 16" long).  Shelves and ladders are rearrangeable and removable. The tube frame construction provides almost 18.5 cubic feet of interior space. This cage has two large front doors (15.5" x 18”), one on the top right side and the other on the bottom right side (left side does not open). Each door has a strong metal lock. Entry hole between levels measures 5.5" x 6.5".

Wheel Size: 8M, 15mm thread or 5/16 inch.

*Warranty: This product has a 30 day return period and limited 60 day warranty. The wrought iron frame is built to last and the powder coating helps withstand rusting for years but is subject to regular wear when exposed to moisture, urine, feces, etc. for extended periods. Wiring is not guaranteed to hold up to excessive or forceful chewing of animals not listed above. Replacement parts are available for separate purchase.

I went back and forth about buying this cage because of how expensive it was but after getting this thing I could not be happier. The quality of the cage shows from the moment you open the box. It goes together with ease and it’s super solid. My chins barely make any noise running around in it. Don’t hesitate for a second if you’re thinking about buying this cage it’s well worth the extra money. -Donald S.

Excellent cage for rodents. I have degus and they love it. The only thing preventing a 5 star Rating is they kick bedding out of it and there's no cage guards made for the cage. We made our own and it helps alot. Some bedding still escapes. Good things is there are no plastic pieces that can be chewed on the entire cage!! -Connie P.


by on November 5, 2019

Using for my new baby chinchilla. The bar spacing is perfect as she can't escape like the last cage we had. I got the ramp cover for the ramp between top and bottom section to protect her little feet. Works great. Other ramps not on as chinchillas jump quite well. Lots of room and the set up was easy enough. Just know, this comes in 2 boxes and they might not be delivered together. -Dorothy R.


by on October 29, 2019

I love this cage for degus. The only reason it's not 5 stars is they kick bedding out of it. Is there cage guards that fits this cage? -Connie P.

[Response from Seller: We are currently designing cage guards for but currently there are not any available. You can try installing plexiglass or wood edges yourself, this has worked for many other customers.]

This cage is the best! This is the best investment I've made for my degu, he absolutely loves it. And it's pretty easy to clean, the hardest part is cleaning the shelves. I am so excited to be getting another degu this weekend now that they will have plenty of space to play. Exotic Nutrition is the best website I've used for everything Degu! -Curran K.

It works great for what I need it to, I ordered the Accessory Kit #GA13221AKIT and Corner Metal Platform . -Olivia H.


by on August 9, 2019

The cage is a nice size and gives animals (if you have multiple) their own space while allowing them to also interact. Unfortunately many screws stick out. Although they are flat, I worry that some animals could hurt themselves on them. Overall very happy with it and pairs lovely with the Corner Metal Platform (sold separately) that I felt were too thick/big for the Congo cage. Do note that the cage ships in two parts so you may receive them on separate days. Only other gripe is the stairs attached to middle platform, you have to remove them to clean the trays and they can be a pain to reattach. -Kaitlyn H.


by on May 8, 2019

Too expensive for the poor quality metal. Before my first cleaning of the cage. The screws were stripped because the screw holder in the half level platform had gotten loose, staying tight to the screw but not the level it's attached to. Forcing me to maime the cage just to get it out. There is no fixing that problem unless I get a new shelf. So now I only use one. I also use wood plank shelves (from the pet store) and my 1.5 lb. chinchilla somehow weighs it down so much that a bar has snapped off. He enjoys his home so it's whatever. But paying over $200 for it to not stay quality for more than a few months is completely ridiculous. -Louis D.

[Response from Seller: We're so sorry to hear about the issues with your cage. Please contact our team directly at sales@exoticnutrition.com for assistance. Thank you.]

I just got my cage put together, easy assembly. Very sturdy, great quality. Best investment I ever made for my chinchilla. She loves it, there's so much room for her to explore and play. Thank you! 🙂 -Jeanie B.

I am a bit disappointed in this cage. After spending $200+ dollars on this cage because it was all metal and stated it was chew proof and will last the lifetime of my pet. Well in less than 6 months a piece of the cage wire broke and my squirrel can stick his head through the gap it leaves and I am afraid he's going to get his head stuck and come home and find him dead. I have had several of the cheap cages and he's chewed up the plastic shelf but the wire has never fail. Well here is my first update; they wrote me back telling me that the cage wasn't designed for my ground squirrel...or prairie dog as some call him, but they said they would sell me a new panel! The funny thi...[Max characters. This post has been cropped.]

Good cage with some minor flaws Hinge for doors is a bad design had to buy some washers, 1 of the 4 wheel casters didn't thread into the base the hole was drilled to big i am going to either weld it on or use epoxy. And locks don't line up perfectly. Little disappointed especially when spending $200+ on a cage. -Caleb R.

[Seller Response: We apologize for those issues! Please contact us directly by phone or email about any product defects, we're here to help! Thank you.]

Absolutely love this cage! Very well made, good quality and spacious for our two rats. Putting the cage together was a bit time consuming but I was able to do it on my own. It is also easy to clean. -Viktoria S.


by on October 25, 2018

This was my dream cage for about four months and when I got my first job over the summer, I spent about 2 paychecks on this cage because I loved it so much. I have only had it for about two and half months and today one of the bars broke. I am extremely disappointed. You would think an all metal construction would be reliable and last a lifetime, but it seems I was mistaken. -Shandril W.

[Seller Response: This product was within the warranty period. A replacement cage panel was shipped to replacement the damaged bars. We hope this resolved the issue, enjoy your cage!]

We have 3 dumbo-eared rats that have escaped from every enclosure I have bought. Except this cage. This is the Fort Knox of rat cages. Well designed and easy to build. Very easy to clean as well. Great product. -Limor M.


by on October 22, 2018

I bought this for our pet squirrel. It is extremely well made... all parts are coated textured metal (i.e. no plastic). It is durable, easy to clean, easy to put together, and the 4 level version has lots of room. Was very surprised at the high quality. -Jeffrey S.


by on October 10, 2018

The 4 level mansion is top of the line, best cage ever!! In fact, we were so pleased that we ended up buying a 2nd identical cage! They are perfect for our opossums!! We also purchased insectivore diet, opossum complete, and berries and bugs. Our skunks and possums are loving these foods and give their new diet "thumbs up"!! We will definitely be back for more!! Also, delightful customer service!! -Sandi B. C., Iowa


by on September 3, 2018

Once built we really like the 4-level mansion. Instructions could be a little better - took us about 2.75 hours to do as a couple of pieces had to be moved. To make this the ideal cage - need some type of barrier around the cage to keep bedding in. -Terri G.


by on August 17, 2018

I am using this cage for 2 Degus. They love all the space! I love that they can't chew up the metal trays! My one concern was them kicking their litter out of the cage and on to the floor. Therefore I cut and attached a 5" tall piece of plexiglass around the lower base. It worked great! -Dan H.


by on July 25, 2018

My mansion cages arrived in a timely manner. Although the paper instructs were kind of difficult to follow I got everything together just fine in about 2 hours. My female chinchilla loves her new home. And now I'm thinking about getting her a buddy, being there Is tons of room in the cage. Didn't come damaged or with missing screws or bolts. Very satisfied with this purchase and would definitely recommend this cage to anyone with a chinchilla. -David P.


by on June 7, 2018

I do absolutely love that this cage is all metal - the plastic garbage on the market is just that - garbage that cracks & stains. This cage is also extremely easy to clean. My only complaints are the ladder going from the 1st to 2nd sections comes off easily & is somewhat heavy bringing serious concerns for my sugar glider’s safety should it fall on them & there is a very sharp edge on one of the corners of the cage. I also would have appreciated assembly instructions as the paper only showed what was in the box but did not explain what went where. -Hope

This cage is fantastic! I have 3 little rattos living in it now and this cage exceeds all expectations I had for it. It is incredibly sturdy with its fully metal construction, very spacious, and well engineered. I never have to worry about my rats escaping and they are much happier in this new cage than their last. It took about an hour or so to assemble (not difficult), and was well worth the effort. I’d recommend this cage to anyone looking for a strong, happy, spacious home for their little critters. 10/10 -Cole D.


by on May 30, 2018

Very nice cage. Easy to clean. Very easy to put together. Love love love. I do wish it had double doors to open like Critter Nation but I rather have metal trays vs plastic trays. -Lorraine M.


by on May 29, 2018

Perfect, I recommend -Gerardo V.

I love it! Everything I wanted except I wish you offered the fleece liners for it too. -Alexandria K.


by on May 16, 2018

I purchased this cage for my prairie dog. He loves it! Plenty of space for toys, bedding, & feeding! I love the pull-out metal trays (he is a chewer) and ease of cleaning! It is also very well built & very nice looking as well!!! -Lanna S.


by on May 11, 2018

I love this cage. Very Sturdy and well built. Plenty of room for the rats that I plan to get and it is chew proof. Very sturdy wheels and easy to move around easy to clean! Easy to put together. Buy it today It is a great cage! -Robyn F.


by on May 7, 2018

I've had the cage for two months now, ever since I unexpectedly received a second chinchilla. It was very easy to put together, and I've always had a good experience with the company. It shipped pretty fast, and is very light weight and easy to roll. Right now I am actually only using the bottom half of it and the top half for storage until my baby chin gets older. The bar spacing keeps baby chins from getting through, the solid metal pans in the bottom mean no chew hazard for the chins. Easily outfitted with many wooden ledges. Highly recommend this cage; however, I removed the wire ladders as chins sometimes get their feet stuck, which can be dangerous for them. -Lauren


by on March 24, 2018

Our chinchilla loves her new cage. This cage was very easy to assemble, arrived undamaged, and fit together perfectly, nothing needing to be rigged. There is plenty of space and room for her running wheels, bowls, and toys. This cage will last throughout her lifetime and then some. Rolls easily, the spacing of wire prevents chewing outside of the cage. So far, the bar ramps have not been an issue. Very pleased this product is chew proof and without plastic. Strongly recommend this product. Well worth the money!! -Jen L.


by on March 13, 2018

I contemplated cheaper options and finally decided on this cage and I am glad I did! This cage is very well-constructed and sturdy. Looks nice too. My rats love it! -Kira


by on March 12, 2018

Easy to assemble- screwdriver needed (directions did not mention it). Great size! Easy to roll. Cleans easy! -Rebecca M.

I purchased this for my chinchilla Zoey an she loves this cage. I had to modify the cage to some degree for a chinchilla. The ramps are nicely built but the are bar ramps. The design of this mansion is better than I have seen on my search for a cage like this. The bedding pans and shelfs are steel not plastic which I was really pleased about. Chinchillas chew plastic... But most manufacturers of cage for small pets always use plastic or have bars for the floor not great for small pets feet. The modifications I am doing for this system is much less than I would had to for other brands out there. I would recommend this cage system to anyone looking for this type of a cage. -David


by on March 1, 2018

Excellent cage for rats and other small pets. Spacing between the bars is 1/2" so nobody is escaping! We bought this model because it is all-metal construction, no plastic. All pieces fit together well and are secured with machine screws into threaded inserts so no wrench needed. All surfaces are smooth and powder coated, We got the two-story model which is more than enough room for our 3 pet rats. We like the slide out trays which make cleaning easier - these are sturdy sheetmetal with about a 1- 1/2 '' lip. All around an excellent well-built sturdy cage.


by on February 27, 2018

This cage is really well built and very secure. I love that it is all metal. It houses my two degus which really enjoy all the room and play space. Also easy to clean. This cage is well worth the money Love this cage


by on February 4, 2018

Love this cage


by on January 30, 2018

I haven't had any issues with my adult rats being able to chew through these bars and they do try. -Cybill Murillo


by on January 30, 2018

High quality product. Definitely worth the price. Easy to assemble. My 2 Chinchillas love it. I keep them separate from one another because they don’t get along. -Phuong W.


by on January 27, 2018

This is a great cage for my rats. The set up wasn't bad at all, but I does go along better with a helper. It is well made and solid.


by on January 8, 2018

This is what I expected when I ordered. A fantastic cage. Easy to assemble. Well made. I am loving the quality from the latch to every inch of the cage. I had one area I had to deal with. It looks good in any room and you don't have to hide it. Shows like a mansion! Just a perfect cage. Buy it!


by on January 8, 2018

Received it before its estimated delivery. Was shocked at how well made and heavy the pieces where. The rollers are well built and roll very smoothly. The size is a perfect size for my furry. The cut out has smooth edges, the 3 ladders are very well built and the animal safe powder coat is amazing. The two doors are a very good size and I can reach all areas of the inside with no problem and it makes it really easy to clean. The spacing between the bars is 1/2 inch which is perfect for small or large furrys. It is very nice to buy something and it be totally worth every penny spent on it. I would not hesitate to recommend it to anyone that wants to purchase something really solid and well built. I did not hesitate to give it all 5 stars!


by on December 4, 2017

I will start by saying that I am not a fan of China made products. Where possible I look for items made in America! That said, this kit was extremely well made, looks great and was straightforward to assemble. When assembled, it looked just like the picture and functions as designed. In the cages packing, everything was protected and not a single ding or damage. That's the way it should be. So my hedgehog (Junior) now has a mansion to live in and it's something that's easy to use and clean.
