The Kuranda Cat Tower is a great way to provide exercise and amusement for cats. Providing this active play area with great look out spots relieves stress and boredom for indoor cats. The staggered levels provide cozy nooks that help provide privacy and reduce conflict between cats. The tower is designed with more weight at the bottom to keep it secure from tipping. The Furniture Grade PVC frame and solid vinyl fabric is durable and easy to wipe clean. Pictured is a 4 tier cat tower.
