I use shredded paper / straw / woodshavings as bedding for my piggy - does she really need hay as well?

YES! Hay is essential for your piggy to provide roughage (for a healthy digestive system) and also to grind her teeth down to prevent dental problems.

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.
