Rubester
New Born Pup
Once we bought our guinea pigs a new cage with two floors but it turned out to be totally useless as they were too afraid to go down the slope leading to the lower floor. If you were planning on buying a new cage I would advise testing it first with your guinea pigs to see if they like it or not. This is not the case with all guinea pigs, maybe it's just because our guinea pigs were afraid of heights.
