The Rainbow Kitty Play Tunnel is a small animals delight for hours of fun. This 13 inch diameter tunnel stays open by a series of rigid, spring steel rims imbeded in the fabric at 8 inch intervals for its entire 48 inch length. The outside fabric is strong, easy to clean nylon and the inside is lined with a soft, wool like material which enhances your pets tactile enjoyment. The entire tunnel collapses for easy transport or storage and 4 attached straps on both ends are available for adding additional tunnels.
