After letting my guinea pigs stay in the cage for a while now I notice that they really love the extra space. The good thing about this cage is that you can get more than one and attach them. For two guinea pigs one cage is more than enough, if you have three you'd probably need two. The reason I subtracted a star is only because of the canvas bottom. The canvas bottom is the reason why the cage is so affordable, but at the same time it's pretty hard to stop them from chewing on it. Also since the bottom is canvas when finding a place for the cage to sit you'll have to make sure the surface is at least the size of the cage or greater. The cage is 4' by 2'. So if space isn't a huge issue and you don't mind a little chewing you can't beat the price and quality of this enclosure.
