A cat tree is a multi-level structure designed for indoor cats to climb, play, and rest. It typically features platforms, scratching posts, and cozy hideaways, providing a stimulating environment for cats. These structures help satisfy a cat's natural instincts to climb and explore while also offering a safe space to relax. Cat trees come in various sizes, shapes, and materials, catering to different cat breeds and living spaces. They can be made from wood, carpet, or sisal, and often include toys or hanging elements to engage cats. A well-chosen cat tree can enhance a cat's quality of life and reduce destructive behavior.
