We got 2 guinea pigs a couple of months ago and they are in a cage indoors. I had been putting down woodshavings then some hay, but have read loads of stuff that says woodshavings aren't good for piggies. Today I've cleaned them out and put down newspaper just in whole sheets and some hay on the top and a bit of Carefresh (?) in the corners where they wee. Is this better for them? They ran around looking like "where the f$@k are the woodshavings?
What do others put in their indoor cage?
