The basket is nice and big so my boys can snuggle together with room to spare. Having said that, my cats are quite small to average sized cats and they managed to have part of this tower snap before I even finished building the thing. The lower hammock level snapped when one of them jumped from it. I can’t imagine it being strong enough to handle most peoples sized cats. Also the little ball on a spring doesn’t screw into its hole so that part went into the garbage; the threads didn’t match up.
