Critter nation shelf size

[melbur10]

Hey guys I'm making shelves for a customer and need exact measurements. I have the dimension for the back wall (34 3/4" -make the shelf 34 1/2") but I need the measurements for the side wall (from the back bars to the front door bars) so that i know it will fit inside... Can some one help?

I have a dimension list on my site under the Info/DIY section for the shelves when I cut all of mine, they're spaced enough to allow doors to shut and all of that.
