I waited a few months to review this one. I got this litter box to prevent our dog from eating the cat's litter. Well, my 55 lb dog managed to A. open the front flap (we had to add a latch) B. Squeeze through the small opening and weasel her way into the box area (Had to add a wood divider to avoid her doing this). Overall, if you have a genius, sneaky dog, you may need to make some adjustments like I did. Also, the front flap used to be more soft-close and now it thunks open on my foot and has cracked the front bars because, let's face it, it is not made that well. Overall, nobody knows this is a litter box, which is kind of the point. I like the look of the piece, but it isn't made great and it did take a bit of time to figure out how to put it together- in my case backwards at first. Overall, I am happy with the design and functionality and the cat took to it immediately and that is what matters.
