The set includes a space cover, a frame, 4 suction cups, a base, size: 45*37*31cm. Easy installation without any tools. The perfect match to keep your cat comfortable and fun at home. This is the best choice for a cute cat as a Christmas gift. Extra strong and specially designed large suction cups for this mounted cat bed window seat can hold up to 50 lbs. 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 release tension and improve/stabilize the suction. After that, your pet can use the seat more safely. SPACE SAVING: A 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. Great for cats who love to bask in the warm sun, or active cats who need a higher perspective. Tips: The suction cups are made of high quality PVC material. When the room temperature is too low in winter, it is easy to harden and cannot work properly. As mentioned above, putting in hot water (above 80 degrees) for 5 minutes will help restore good suction.
