Since baby guinea pigs are so small and tiny it’s always a good idea to take more precautions to help to make them safe while they are in their cage. Take their little heads for example, their heads could easily become stuck in between the bars and this would lead to asphyxiation. One way to prevent this from happening is to line the cage walls with cardboard from the bottom up to around one foot. If your cage is made from wire grid, then you could add a new wall by placing more grid on the outside and then putting cardboard in between the two cage walls. After the babies have gotten to be around 4-6 months old this extra wall or cardboard can be removed. They have now gotten big enough to not worry about their little heads becoming stuck.
