- Durable Natural Sisal: Wrapped in high-density natural sisal, this cat wall shelf is designed to withstand scratching and wear. It provides a perfect surface for your cat to exercise, sharpen their claws, and keep boredom at bay, saving you money on scratching boards. - Comfortable Curved Design: The shelf features a curved concave surface that allows your cat to relax comfortably while basking in the sun. With no overhead obstructions, your cat can jump on and off easily, making it an ideal lounging spot. - Sturdy and Safe Construction: Built with a solid pine wood frame, reinforced by upper and lower iron brackets, and secured with four high-strength PVC suction cups, this window bed can hold up to 30 lbs. When properly installed with suction cups aligned, it ensures maximum stability and safety. - Easy Installation: Simply attach the four suction cups to the ends of the upper and lower brackets, then secure the lower bracket to the upper bracket. This versatile design allows installation on smooth surfaces such as glass, ceramic tiles, stainless steel, and mirrors. - Installation Tip: For optimal suction power, soak the suction cups in warm water (at least 60°C) for five minutes prior to installation. This is particularly helpful in winter when suction cups may harden and lose effectiveness. - Use Scenarios: 1. Place the shelf in a sunny window for your cat to enjoy sunbathing. 2. Install it in a common area to give your cat a vantage point for watching the world. 3. Use it in a multi-cat household to provide a dedicated space for each cat to relax and play.
