As I sat here with a cavy on my lap I thought of this thread. My cavy herd is at four now. I really only meant to keep the girl to be a companion for Christie. The placement of one of the boys didn't work out and he came back home. After really falling in love with him he got a really great Christmas present - a companion. So now my cat Shadow has two little cavy sisters and two little cavy brothers. And my living room always has pine bedding and hay scattered all over the place.
