I'm new to this forum, but not new to guinea pigs. My name is Becky, and I'm the mom to 3 humans (husband included ) 2 rats, 1 ferret (who lives in a C & C cage) 1 hamster, 1 incredibly fat cat, and 11 guinea pigs. My in-laws have 4 guinea pigs that I take care of, and I'm about to drive along with my friend, a fellow guinea pig owner to Northern Illinois to get another guinea pig, rounds me out to an even dozen.
