The pictures on this page are of pet guinea pigs. They all live at Tremont School except for Marshmellow who lives at Evan's house.
Guinea pigs are cavies.
They are rodents with very sharp front teeth. Their teeth never stop growing and are used for gnawing. Guinea pigs seem to be timid because they are always alert, and run and hide when they are startled by sudden movements, strangers, loud noises and strange surroundings. They are very affectionate once they get to know you. Guinea pigs come in many colors and patterns.
