Made from Cagetopia Standard Grids and Cagetopia Door Grids. This can expand into any shape -- circle, square, rectangle -- and adapt to irregular locations. If you have a wall or a corner to use, this can give you all the more to block off for their Camp Cavy!
This opens up to a little over 16 square feet of space or the equivalent of a 2x6 or a 3x4 grid cage. The inner ring is a 2x2 grid area (or 5+ square feet). The inner alternating door grids are the secret sauce to making this a fantastic playground setup for your guinea pigs.
