I was in the local pet superstore yesterday and noticed they had this big sock thing in the guinea pig enclosure. A guinea pig would go in one end, and a minute or two of rummaging around later would emerge at the other end. Sometimes a group would go in together and emerge in nothing like the order they went in. It reminded me of a particle accelator. Just think of the hell on guinea pig earth inside there, the gamma rays and sodomised electrons bombarding their poor little bodies tossed this way and that. And all in the name of so-called 'science'.
