I just wanted to mention that the baby section in department stores can be a great place to find guinea accessories. The other day I found a head holder thing (I think its original purpose had something to do with a car seat) that serves perfectly as a cozy. I also found nice colourful rings that hook together, perfect for hanging in the cage so the pigs can knock them around with their noses. They also had really nice small fleece blankets, and various other snuggly cuddly things pigs might like.
