A room in three levels
Long ramps link the loft, gallery, and climbing tree. Low platforms in the wider south wing offer gaps, hurdles, and angled landings.
Each cat has food, water, and time to rest between practice rounds. They look towards neighbours, exchange slow blinks, and keep landing spaces clear. Each mouse has food and water delivered inside its refuge. Supplies are replenished by the room caretaker.
The cutaway opens the view. The room stays closed.
