I use this mostly as a perch for my cat, I have  it right by the patio door in the living room. PROS:I live in an apartment, and it doesn't take up much floor space. I feel the tree is well-made, and a good value for the price. It was easy to put together. My cat is small (8 lbs.) and it's the perfect size for her. CONS: My cat used the sisal-wrapped legs at first, but doesn't any more (don't know why). She doesn't use the little "cave", but will go in once in awhile. The shelf above the little "cave" is a little too small for her. The vertical piece holding the top shelf shakes a little when she jumps on it. I probably would buy a shorter tree next time, since she doesn't go up on the tall shelf much.
