Update: it got wet and the particle board disintegrated. Difficult to clean in the grooves. Disappointing as this was an expensive purchase for us.

Perfect size for extra large litter box (without the interior separator). The access door can be installed on either side which is perfect as we needed it to be on the right side of the enclosure. The downsides are: some of the instructions which were confusing because some weren't holes pre-drilled; the wood material cracked when drilled.
