I have a total of 4 guinea pigs. Two females live in this guinea pig habitat. It is definitely very spacious. The guinea pigs seemed to love it right away. I actually had a third female living in here as one of my females had babies and I had them living with their mom. As they grew though, there was definitely not enough room for a third pig in this home. It does, however, comfortably accomodate two. The only downside to this product is that I do think it's a real pain to clean. Instructions state not to put the canvas in the dryer, but I have been sticking it in there on no heat and it has been working for me. All in all, it's a great product and seriously, who could be this price? I have spent well over $100 for other homes.
