I see a lot of pictures online of people who give there piggies beds, put a fleece blanket at the bottom of a cage etc. My experience with guinea pigs is that they eat all these things. My previous guinea pigs ate some of my sisters carpet and cardboard boxes were also eaten. So now I am a bit afraid to give my piggies things that are not wood or very hard plastic (that is almost impossible to chew on). How do guinea pig owners keep there piggies from eating everything because I don't think fleece and other things like that is very healthy for them.
