I would not refer this product to purchase.  The whole thing is of really really poor quality.  the doors look like they were 50 years old, the paint is wore off.  You need to cover the top as it is not pretty at all since you literally screw the sides in from there, so you see the screws.  So weird!  My cat can push open the doors from inside, so there is always a mess as he opens the two doors and jumps out there.  Poor engineering on that part.  It needs a lock on the outside, so I will probably have to put a rubber band around the knobs to keep it shut.  Really.....
