We offer you a new design, exclusive to the Rat Warehouse, The Urban Fluffbum hammock is a cozy black hammock lined in soft lambskin-like fleece fabric and covered with a black/purple/light blue Urban Camouflage fleece blanket layer. Your Rats can sleep inside or on top of this comfortable hammock. This particular design provides vantage points at the front and back by the bars which tend to discourage window-making efforts by the curious and creative rattie. Measures 13x15 inch excluding clips.
