First of all, if you have questions such as the two you have posted, use the Search function here on the Forum and you will find the answer to just about any question you may have. It is the box at the top right of the page with the magnifying glass. You will find a wealth of information in previous posts. When I first joined the Forum, I literally spent two days reading through old posts in order to get up to speed with the present discussions.
There will be a problem with the 8x8 grids only if your cavies can come in contact with them. As you know, babies are especially vulnerable to getting a head stuck in the grids. For instance, there is NO place in my cage that it is possible for them to ever contact a grid. When assessing for this, be aware that cavies often climb on houses/hideys that are close to the side of the cage. I had a 4 wk old actually climb up on a house and jump out of the cage because I had to isolate him in the loft for a couple of days. Thankfully, I found him wedged in the cage stand and he was o.k.
Most of us make our coroplast walls about 6" high, but there's no harm in making them 8" or even a bit more. Look at it this way: you can make the walls higher now and when your piggies get older, you can always cut them down. Some people babyproof by wedging cardboard between the coroplast and the grids when the piggies are young and then remove it later. It's not very esthetically pleasing, but it works.
In conclusion, if you need to use the 8x8 grids, I feel the best solution is to make the walls higher. And BTW, the 8x8 grids are perfectly fine for the cage bottom and for a grid stand.
:important Please help. I don't get my guinea pigs until next month but I'm trying to be well prepared.
