Medium Cage Dimensions
- Interior: 27" x 50" = about 9 Square Feet of cage space.
- Exterior: 30" x 54" when assembled with grids (not included in this item) you will need a table space of about 2.5 feet by 4.5 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
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.
Coroplast Base Includes
- 4mm Coroplast bottom in your choice of 15 colors!
27" x 50" x 6" sides for 2x3.5 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 2x3.5?
- 1-2 guinea pigs. This cage is too small for 3 or more guinea pigs.
- 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.
