Anything & everything, so if you have one or more as pets you have to be fairly vigilant as to what is in their reach. Guinea pig molars never stop growing, that's one reason for the gnawing on everything. Guinea pigs are also mammals that are aware of changes in their environment - so, curiosity is another reason for the chewing.
FYI - Plain wooden objects (no paint), plain paper (or paper with soy based ink if scrap paper is used) and cardboard are good things to put in a cage for guinea pigs to gnaw away at.
It is spelled "guinea pig". You got it right! :)
