This so called jungle cat walk has nothing for active cats to do. Holes are very small. Would never pay this price for just shelves with holes.

It looks like a small to medium sized kitten or young feline might be able to jump up & possibly squeeze through this device's 'holes', but when most cats start to settle into maturity, they sometimes get larger or simply a roundness & become less active & I believe this item to be a total waste of $$$! Get a good cat tree that will last throughput your cat(s) lifespan, one with several flat or large places where it can stretch out, or as I refer to it with my now nine year old kid-cats, they like to veg out! They really like to claw the posts & jump up & down the various levels & hidey-hole areas! Most cats have behavioral activities that produce a feline that might weigh (,like my Calico/Siamese mix) upwards to 21-24 lbs & might still be as active as a kitten to a lazy beast, but this device would not allow this type of activity, in my opinion!
