The Cagetopia (3x3 grid) single-level, uncovered C&C cage measures 44"x44" when assembled, and gives the guinea pigs 41" x 41" of space with 3" walls. Each size up adds more space. See the chart below. Our Coroplast bases are secured with reusable plastic rivets. The 3x3 cage is suitable for 2-3 guinea pigs. The walls are 3" instead of 6" because sheets of coro are only 48" wide, so 3+3+41 (for a 3-grid span) = 47" of coro width (out of 48) needed.

The 3x3 cage provides about 11.7 square feet of space, as compared to the 10.5 sq ft of a Large 2x4 Grid Cage. More room for the guinea pigs, but more hassle for you on maintaining it due to reach. You can't really reach all the way across a 3-grid-wide span, so you need to have plans or a mindset to manage that. The piggies will like it! Because of that and the overall size, these are best used on a floor. 

The 3x5 cage is shown in Cool Flame coro color.

Cage Kit Includes

3x3 Grid Cage

  • (12) 14" Grids in black or white (powder-coated and SAFE inner holes 1 3/8")
  • (24) Connectors in black or white

    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
  • Cable ties that match the grid color. (Using cable ties to reinforce the grid connections helps make the cage extra tight and super secure.)
  • Access to online easy-to-follow, color assembly instructions with photos

How many Guinea Pigs will fit in a 3x3?

  • 2-3 guinea pigs. This is a good cage size for 1 or 2 guinea pigs. This cage is still a bit 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.

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.
