Guinea pigs *must* have vitamin C. You could try selling it to someone who has rabbits, or give your guinea pigs extra vitamin C - buy some from a chemist.
You should never feed a guinea pig rabbit food. It is too high in calcium and can give them kidney stones. I have no idea why people on here have been telling you it is okay.
They should not comment if they do not know what they are talking about. You said you cannot buy more guinea pig food but this is not good for your guinea pigs.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
