    Item #: CAGE-MD
    Availability: In Stock

    Medium Cage Dimensions

    • Interior: 27" x 50" = about 9 Square Feet of cage space.
    • Exterior: 30" x 54" when assembled = you will need a table space of about 2.5 feet by 4.5 feet to accommodate this cage.

    Medium Cage Assembly

    On the Medium size cage, the two middle grids are partially overlapped and secured with cable ties to accommodate the stated length to provide a cage size option that might better fit your space and/or budget requirements.

    Coro Height Preference

    This refers to the HEIGHT of the COROPLAST on ONE long-side of the cage -- for the back wall.

    • 6" (inches) is standard. 6" sides all the way around maximizes ventilation and visibility, and it is generally high enough to keep in bedding for most guinea pigs. Also, a water bottle spout resting on the top of the 6" Coroplast is a good height for guinea pigs to drink from.
    • 12" (inches) is good if the long side of your cage is going up against a wall. This helps prevent hay (and in some cases bedding) from being kicked up and getting stuck against the wall. You can always cut it down later if you decide it doesn't work for you. The 12" option is just to help you keep your floor and wall cleaner in some circumstances.

    NOTE: We do NOT offer 12" walls all the way around because we do NOT recommend it. It cuts off too much air circulation for the guinea pigs. In addition, even if you wanted it regardless of our advice, coroplast is only 48 inches wide and that would require 51 inches.

    Cage Kit Includes

    • (12) 14" Grids in black or white (safe grids with 1 3/8" openings)
    • (20) Connectors in black or white
    • 4mm Coroplast bottom in your choice of 15 colors!
      The base is cut and scored so you only have to secure the flaps. (Coroplast base is scored and folded for shipping, which makes an indented "crush" line, but it does not affect the function of the cage. It's barely noticeable when fully assembled.)
    • Cable ties that match the grid color. (Using cable ties to reinforce the grid connections helps make the cage extra tight and super secure.)
    • Easy-to-follow, color assembly instructions with photos
    • Two-page Guinea Pig Care Sheet

    Please NOTE about the Cage Bottom

    The cage does not have grids on the bottom. They are unnecessary. The cage is designed to sit nicely on a flat surface -- a table top, a desk, the floor (if it's draft-free), etc.

    However, if you desire, you can make a cage stand out of grids. Please see our matching Medium Cage Stand if you are interested in a cage stand.


    We include detailed instructions with every kit, but if you have questions, we are always more than happy to help you out! Just contact us--pop us a note with your phone number and we will call you back as soon as possible with in-person assistance!


    Please do not put the Coroplast directly on a hardwood floor. Moisture from the air and/or wood can get trapped and has nowhere to go and hence can cause sweating -- which has NOTHING to do with the quality or character of the cage. Nor is the cage leaking. All you have to do is put something absorbent down first like a towel or carpet and set the cage bottom on that instead of directly on wood.

    NEW! Rivets on the Flaps!

    • We've updated our cage design to make it even easier and more secure than ever! All of our Coroplast bases now come with nice, clean holes -- professionally punched in the appropriate locations. We include our new, easy-snap-in plastic rivets for securing the base. 
    • The rivets, while very secure when in place, can also be popped back open with a little separation pressure should you need to dissemble your cage and are generally reuseable.

    I KNOW this cage will fit in my space!

    I've read the cage dimensions and have measured my space. GRIDS are 14", NOT a 12" FOOT! For example: 2x4 Grids needs 2.5 x 5 FEET of space.

    Perfect Cage!

    my sister bought a guinea pig a long time ago, and after she got bored of her, i offered to take her and take care of her. sadly, she was in a really tiny fish tank cage, and i knew that was absurd and i needed something better to keep her in, so i bought this cage and the upper loft for her and its perfect. she tried to chew on the sides, but they also have edging for that, so i just bought that to curb her habit of chewing on it. plenty of room for her to run around, and very easy to clean, very nice and neat design too. was super easy to assemble too, im an idiot when it comes to putting things together and even i could figure it out.

    Two Happy Pigs!

    I bought the medium cage with the stand for my daughter's two baby Guinea Pigs. I put it together with 4 little girls helping me. It took about an hour or so. I never put stuff together, I usually just "assist" my husband. It was very easy to do, the instructions were clear and easy to follow. We look forward to expanding their cage in the future.


    My Guinea Gals Thank You!!!!

    <p>Purchased the Medium Size Cage for our girls Molly and Leesha, they are popcorning and exploring like crazy. Pink Coro, white grids with a Purple Cavy Kitchen. Could not be happier. Looks amazing, and coordinates with my daughter's bedroom perfectly, Will be so easy to keep clean compared to our old setup. Shipping was super fast, very easy assembly. Thank you!</p>

    <p>I LOVE THIS CAGE, It stays very clean, they have plenty of room with two litter boxes, house and dishes. I would recommend it. Easy to put together. Just need the space and table big enough. I had to put two folding tables together for it. I guess you can buy the C&C stand.</p>


    Great cage!

    I bought this cage because the store bought one I had for 2 years wasn't cutting it anymore and I'm looking into finally being able to adopt a cage mate for my guinea. I just got the package a couple of hours ago, and had it put together in no time. I am so happy with it and so is my piggy! very roomy, I don't know how I used the one I had for so long. I'd highly recommend these cages :)
