The Bio Bubble bungalow converts the Bio Bubble into a fun multi-level loft environment for gerbils, mice and other small animals where they can play, nap and exercise. The bungalow comes with a durable ABS deck, washable hammock and an exercise ladder. Use the BioBubble Bungalow with any BioBubble Riser when creating habitats for these small animals. Risers can be stacked and multiple Bungalows can be used to create even larger fun habitats for all small pets. The upper level bungalow allows for exercising, playing and napping.
