    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 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


    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.

    Coroplast Base Includes

    • 4mm Coroplast bottom in your choice of 15 colors!

      27" x 41" x 6" sides for 2x3 Grid cage
      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.)

    • (16) Snap-in Plastic Rivets to fasten flaps.

    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.

    How many Guinea Pigs will fit in a 2x3?

    • 1-2 guinea pigs. This is the MINIMUM cage size for 1 or 2 guinea pigs. This cage is too small for 3 or more guinea pigs.
    • ONE guinea pig needs at least a 2x3 grid-sized cage. TWO guinea pigs who get along well can also live in this 2x3 grid-sized cage. Although we do recommend a larger cage, this will suffice.
    • The 2 guinea pigs should be a BONDED PAIR. If you have two new males who have not been together yet in a pet home, then in all likelihood, this cage will be too small. Or if you have two guinea pigs who do not get along -- either they bicker all the time or occasionally -- then this cage is too small.
    • This cage size may not be divided to accommodate two guinea pigs who do not get along, nor is it appropriate for separating two guinea pigs of the opposite sex. It is just not big enough for that.

    Guinea Pigs should have a Friend

    Just a note that guinea pigs are a social, herd animal and are happier and healthier in pairs or groups. If you only have one, please consider the best interests of your pet and adopt a same-sex friend.

    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!
