    This Coroplast base is made from 4mm-thick corrugated plastic and is designed to be used with our Cagetopia grids (14" square) with connectors. This Small size is 27"x41" for 2x3-grid cages. It is professionally cut and scored and includes reusable, plastic rivets to secure the corners.

    Item #: CORO-BASE-SM

    Small Cage Dimensions

    • Interior: 27" x 41" = about 7.5 Square Feet of cage space.
    • Exterior: 30" x 44" when assembled with grids (not included in this item) you will need a table space of about 2.5 feet by 3.75 feet to accommodate this cage.

    Coro Height Options

    • 6" walls on all four sides. This is the perfect height for keeping bedding contained, visibility to pigs, good airflow, and safety.
    • 10" walls on all four sides for Hedgehogs only.
    • 12" long back wall only, three sides are 6". May help keep hay and bedding kickout more contained with active guinea pigs, especially when not using fleece, but generally 6" walls are just fine.

    NOTE: High walls all the way around a cage are not recommended for guinea pigs as it blocks too much airflow as well as your visibility.

    Coroplast Base Includes

    • 4mm Coroplast bottom in your choice of 16 colors!
      The base is pre-cut and pre-scored with pre-punched holes to secure flaps using snap-in plastic rivets (not tape). Coroplast base is creased and folded for shipping, which creates an indented "crush" line. This does not affect the functionality of the cage. It's barely noticeable when fully assembled.
    • Rivets for fastening all coroplast flaps

    Our Cagetopia-brand Grids have stayed the same over the years as we have many hundreds of thousands of C&C cage owners (DIY and customers) that depend on the original sizes and the best quality grids and connectors.

    Supplying your OWN GRIDS?

    Or mixing in different grid sources or vendors? No 14" grids are the same anymore. Please review:

    • Many 14" grids are NO LONGER COMPATIBLE
    • Grid Vendors are now ALL DIFFERENT from each other
      Especially on Amazon, but also Bed, Bath & Beyond, Target, etc.
      • DIFFERENT CONNECTORS: gap spacing (space between grids) can be different (standard = 3/8") and that matters.
      • Grid Size: 14" exactly is required -- NOT 12" or anything else
      • Grid Wire Gauge (thickness): Grid vendors adapt their connectors to their wire gauge, which is typically thinner than ours (4mm = 3 pennies), so they won't work well together, if at all -- too tight or too loose.
      • Inner Grid-hole Size (safety-related):
        NO INNER HOLES BIGGER than 1.5" or you risk your guinea pig's head getting stuck and strangling. In a 14" grid, there should be 9 holes by 9 holes -- never less.
    • Using only Zip Ties (no connectors) is NOT RECOMMENDED.
      Some people complain about using the connectors. They are using NON-Cagetopia connectors. Ours work great and are easy to snap in, while being strong and stable.
      • Zip ties alone ARE NOT STRONGER as compared to using Connectors WITH zip ties (not opinion, engineering fact).
      • Many Cagetopia products will NOT be compatible for fit without using the connectors.
      • The fit of the coro inside the grids will be different.

    Trying to save a few dollars now on purchasing grids separately could be a frustrating, if not an expensive, decision later.

    All these things MATTER on CAGE BUILDING.

    If you buy one vendor's grids today and try to mix in a different vendor's grids from Amazon tomorrow, odds are high they may not be compatible with each other or our Cagetopia Grids.

    Thank you..

    Thank you, it fits and looks great. I'm not sure if it should have came with holes for the rivets or not, and mine did not have holes, but it wasn't a big deal.

    FROM GPCS: Yes--so sorry, it should have had nice, neat holes punched for the rivets. I'll email you.

    Loved it but it doesn’t fit all brands of grids

    I bought a hay holder, a Coro base and a cavy cafe and spent over a hundred dollars, I was so happy that my guinea pigs would have an a amazing cage and fun, awesome, and conventional accessories. But after I built it, the Coro base and cafe was way too big for my c&c cage and nothing I bought fits. I measured it and it said it was 3.4 feet wide and that’s not what the website says, but I could be wrong. I am very disappointed because I just set up their cage one a table that was just the right size for their cage and now I have to buy a new expensive table, build a whole new cage and spend a lot of money I thought I saved by buying this product. I don’t think this product fits all brands of c&c cages

    Second Awesome Purchase

    Replacing two year old cloroplast to freshen up the look of our girl's cage. Originally had a 2 x 4 but wanted something a little bit smaller. I was worried that our pigs wouldn't have enough room with the 2 x 3 with narrow loft but they still have plenty of room. Old base was all pink, this time I decided to go with all navy with pink Cavy Kitchen and I must say it is beautiful. Style of the chew gaurds have changed and are much thicker than old style which I love. Cloroplast is simple to put together and very great quality. I absolutely love this company and their products. Quick shipping and packaged nicely. Guinea Pig Cage Store has made me a life long customer!! Do not hesitate to buy, you or your piggies will not be disappointed.

    My boys couldn't be happier!

    I have two males who do not get along at all, but it is important to me, as well as them, that they be close to each other. I had more than enough grids to make two separate 2x3 cages, so I ordered two bases. Their cages are completely connected, but extra grids, down the middle, act as a barrier, so they both feel safe and comfortable, but can still interact when they want to. I love the coroplast colors I chose, but I also love the fact that I can order other colors when I want or need to, and it won't break the bank. Their room is so bright and cheery now! The bases are literally a simple snap to put together and everyone who meets my piglets or sees pictures compliments their home, the size, the uniqueness, and how happy they are. I love my boys and I love seeing them happy! :) Shipping was also super fast!

    Quality product!

    Exactly what I have been trying to find! Large coroplastic is harder to find than I realized. This solved that problem and the pre-cut product is soooo convenient! Already had grids from a cage made by a friend but desperately needed a new bottom. Order came in efficient time and in great condition. Will definitely turn here the next time I need a new bottom!


    2 x 3 base

    Piggies love it!! Fits in there just perfect!!

    So Happy!

    Just this week I had ordered my two guinea pigs a 2x3 coroplast base. Having already had the grids from a previous 2x4 I only needed to purchase some zip ties to secure the cage even more. I ordered it on Tuesday and just received today on a Thursday, so shipping was incredibly fast. I am even considering buying a whole other level to add on for my piggies. So happy with this product!!! Recommend to everyone!

    Only WAY

    I love their bases! I have owned 2x2, 2x3 and 2x4! All were great! Wonderful quality and easy to put together! I just used clear wide packing take to tape flaps down!

    So excited

    I just wanted to tell you how excited and happy both me and my piggies are with the awesome coroplast that you sent!!! They are so happy with all the extra space!! The youngest of the piggies loves to run laps. And I love that they're happy, and I can be organized with the storage underneath! Thank you so much!!!

    Two girls are in heaven

    I recently bought a sheet of coroplast from Sue. I had the grids, but I could not find corplast anywhere! My two girls are in heaven. They play tag several times a day and popcorn all the time. They are still babies so they get frightened easily, but I think the new cage will help them become more brave. I would recommend them to everyone. It saved me money and space!
