Large CORO BASE Dimensions

  • Interior: 27" x 56" = about 10.5 Square Feet of cage space.

Coro Height Options

  • 6" walls on all four sides. This is the perfect height for keeping bedding contained, visibility to pigs, airflow (ventilation) and safety.
  • 10" walls on all four sides for Hedgehogs.
  • 12" 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 not needed as 6" walls are fine.

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

Coroplast Base Includes

  • 4mm Coroplast bottom 

    27" x 56" x wall height selected
    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 2x4?

  • 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 2x4 grid-sized cage. TWO guinea pigs who get along well can also live in this 2x4 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.
