My cat loves it, after we put it on our widow, my cat stay on the bed for a long time. The dog can't reach it so the cat is safe and can look down on them, very cool!
It's about 12 inches from the bottom of the lower suctions to the center of the top suctions, so be sure to account for that when measuring car jumping height. And it's large enough for my boy to jump up comfortably, he weights 12-13 pounds
It holds my fat girl(shes almost 18lbs) and I was scared to put her on something that seemed so thin and weak but it's holding her fat self up! She loves to be up high so I knew she’d love it
