This thing is awesome so far. My cat hasnt had a chance to explore it yet though (in the middle of introducing my cat to my boyfriends house). Love that the food dish tray is tilted and hinged for easy cleaning underneath. Had to flip the litter box opening because I got a high sided litter box. Im pretty sure my large breed cat should fit as my boyfriends tall cat fit through the opening.

Was super easy and straight forward to put together. Wouldve liked more labeling on the hardware but thats it.
