Great size for outgrown guinea pigs
My piggies love this cabin. Funny enough: They rather lay on top of it (perhaps it gives a better view to potential food arrival;)), then being inside of it. It feels very solid and heavy. It's easy for guinea pigs to jump on it as it has no slippery surface and an easy grip for the guinea pigs. I would only recommend this cabin to outgrown guinea pigs though, because of the open window (small guinea pigs may want to try to go through it and hurt themselves).
