How to Pick a Cage for a Guinea Pig



Get together enough grids for the cage; for two guinea pigs you will need a minimum of two grids wide and four grids long.,
Connect the grids to form the perimeter of the cage (12 grids/24 connectors for a two by four cage, or 14 grids/28 connectors for the preferred size cage for two guinea pigs).

Measure and mark the Coroplast (using a tape measure, yardstick and pen).,
Cut it to the outer dimensions with the scissors or box cutter.,
Measure and mark 6″ in from all sides (the inner dimensions).

Score the Coroplast along these lines using a razor blade or box cutter.,
Cut all the way through the Coroplast at each corner, just 6″ in, to create the flap to make the corner.

Snap the edges away from the score line to form a box.

Secure the flaps on the outside with clear packing tape.,
Place the box inside the connected grids.,
Add bedding, hiding areas, food dishes, water bottle, hay holders, toys, and guinea pigs.

Check that it is sturdy.

Set up the cage indoors.,For pictures to go with the instructions, visit

,, Add 12 inches (30.5 cm) to the length and width for a 6 inch (15.2 cm) wall all the way round. This gives you the outer dimensions to cut (photo is just to give you a perspective). If the cage is going against a wall, you may want to make the back wall 12 inches (30.5 cm) high to help prevent hay spillage. In that case, you’ll add a total of 18 inches (45.7 cm) to the original measurement from above, for one 12″ side.

, A pair of heavy duty scissors or a box cutter is easier than regular scissors, but you can still use regular scissors. Cut lines depend on how big of a sheet you are starting with (partial sheet shown).

,, Scoring with the grain takes less pressure than scoring against it.

,,, A couple of wide strips on the outside work great.

, The cage is now finished.

,,, Outdoor cages are not appropriate for guinea pigs due to temperature fluctuations, high risk of illness and parasites, and the fact that even secure outdoor cages can be gotten into by predators or stray dogs.
