Multifunctional Activity Center: This multifunctional cat tree offers a comfortable condo, soft hammock, top perch and arch self-grooming area. It features a multi-level, staircase-like arrangement so your cats can easily climb to the top. Cozy and Privacy: Equipped with a private and cozy cat apartment, your cats can have a sweet dream. A soft plush perch with a raised edge allows your cat to enjoy the scenery from the window. Healthy and Fun: The extra removable plush ball maximally satisfies the cat's hunting instinct. Covered with natural sisal, the scratching post is designed to fulfill its scratching nature. The brush on the self-groomer gently massages your cat and helps remove and collect hair. This benefits the cat's health and ensures a clean environment in your family. Strong and Stable: Stability is always a priority. Made of soft plush fabric, CARB-certified natural particle board, firm sisal-wrapped posts and a reinforced base, this cat tree is well balanced to prevent wobbling.
