Cage Safety

We use the 'safe grids' -- the inner holes are 1.5 inches. Grids with inner holes greater than 1.5 inches are too dangerous. But, even with the SAFE grids, you MUST BABY-PROOF your cage if you have young or small guinea pigs. Guinea pigs grow very quickly and are usually fine with grid walls at a few months old. But, you have to use your good judgement and common sense. Some guinea pigs are small in size and some have very narrow-shaped heads. In those cases, you may need to make adjustments for about 6 months to be safe.

Baby-proofing a C&C Cage

Baby-proofing is a temporary requirement. You can do a few different things. You can make the coroplast walls higher with some scrap pieces of Coroplast or even cardboard. Nine inch walls will be fine for babies. You can remove the temporary walls when the guinea pigs are large enough. OR, you can use cable ties and some extra grids, you can double up the grids in an overlay pattern, reducing the inner holes by half.

Overlapped grid

To baby proof, increase the wall height from 6 to 9 inches. You can:

  • Use Coroplast (extra or scrap pieces) between the Coroplast wall and the grids to make the walls taller
  • Use Cardboard between the Coroplast wall and the grids to make the walls taller
  • Use Fabric (clipped to the inside of the grids and behind the Coroplast walls) to un-expose the grid holes
  • Use Grids doubled up on the outside to reduce the size of the holes.

All can be removed and reused when the guinea pigs are big enough.
