The design inspiration for this cat tree comes from the movie Castle in the Sky. Our designers combined modern and bold designs to create a perfect place for cats to explore. It's fully covered with sisal rope for scratching, with soft cushioned mats for relaxing. The top layer acts as a multi-activity center with a space capsule nest. The large transparent nest is detachable and replaceable, satisfying your cat’s instincts safely. Keep your furry friends happy and healthy.
