The set includes a space cover, a frame, 4 suction cups, a base, size: 45*37*31cm. Easy to install without any tools. The perfect match makes your cat comfortable and fun in the house. This is the best choice for your cute cat as a Christmas gift. The super strong and specially designed large suction cup is suitable for this installed cat bed window seat, which can hold up to 50 pounds. Before the pet actually uses it for the first time, place some other heavy objects (about 2KG) for about an hour, which will help the suction cup to release tension and improve/stabilize the suction. After that, your pet can use the seat more safely. Save space: The hammock cat bed can provide your cat with a front row view of nature, weather, people and other things without taking up valuable floor space. Ideal for cats who like to bask in warm sunlight, or active cats who need a higher viewing angle. Tip: The suction cup is made of high-quality PVC material. When the room temperature is too low in winter, it is easy to harden and cannot work normally. As mentioned above, putting in hot water (above 80 degrees) for 5 minutes will help restore decent suction.
