This is our 3 guinea pigs' new cage. I was going to do 2 lofts, a 2x2 on each end but decided it would be too crowded on the bottom with the ramps. The tower is a cat lounger that I found at Walmart I then I have an igloo looking house at the bottom to make 3 sleeping areas, then there is storage space at the bottom.... I am open to any suggestions on any other items to add to the cage to keep the "piggies" happy. Right now the 2nd level is separated as the youngest piggy was injured.
