How can I check that every litter cabinet corner is reachable?

To check whether every corner is accessible, look beyond the main door opening and consider the space behind partitions, hinges and the tray. Ask whether shelves or panels intended for routine maintenance can be removed, and inspect how they are secured. You should be able to reach litter or spills without forcing your arm through a narrow gap or tipping the whole cabinet. A photograph of the empty interior can be more useful than a styled image with the tray already installed.

Consider the tools you normally use and where the removed tray will go while you clean. If a corner can only be reached by dismantling structural parts, maintenance may become unnecessarily difficult. Keep the final position accessible too; a cabinet pushed tightly into an alcove can turn a workable design into an awkward one. Plan for ordinary repeated cleaning, not just the first assembly day.

Ask for an interior photograph with the tray removed if the listing only shows styled views. Follow the back wall and both rear corners with your eye; these are easy to overlook when the foreground tray makes the layout appear simpler.
