Back in the day when I owned guinea pigs, I witnessed this
phenomenon:    1. Guinea Pig 1 would run around the confines of
the cage and whack Guinea Pig 2 in the butt, coming to a halt
2. Guinea Pig 2 would then take off, repeating Guinea Pig 1's
actions, and hit it in the butt, coming to a halt   3. Repeat
4. They'd play it in the early morning often, usually at about
6AM.     After that they were seemingly normal abyssinian guinea
pigs.  Log in or registerto write something here or to contact
