I have three grown cats. BB is 4 and weighs 19lbsMini is 3 and wieghs 20, her son Sweet Pea is 1 and a normal 8 pounder. All three absolutley love their new toy! They all sit on it at once, it is sturdy enough for all that weight and doesn't even wiggle or wobble! BB is MaineCoone and so a bit of him hangs off the perch here and there but he loves to sleep right on top! It was also a breeze to put together [...] I can not say enough good about this product!
