My husband was so mad that I bought this lol he said our cat was too much of a fat a$$ for it to stay suctioned to the window. BUT... its sturdy and strong!! Our fur baby is about 28lbs, and he actually jumps into it, it's been up weeks and has not faultered yet!!
Huge plus, we can pull the tubes (the actual hammock is wrapped around pvc type tubes) from the suction cups, and lay it down, or rather let it hang flat against the window to be able to close the curtains at night.
