I have a rat/chinchilla/ferret cage for sale for $150 in pretty good used condition just needs to be cleaned. Was given to my mom for her guinea pigs but this is not suitable for guinea pigs if you ask about this for guinea pigs you will be turned away immediately! If they fall they can break their backs and they need floor space not vertical space just trying to save someone the heart ache of loosing a piggy! I love my piggies and like to spread the knowledge.
