Home Declaration is a Yukkuri behavior, mostly seen in Gutter Trash and Wild Yukkuris, in which a single yukkuri or a family of yukkuris will proclaim its ownership of a den, or even a human house. During a home declaration, usually an adult yukkuri will proclaim ownership of a new "Easy Place"; if its a parent yukkuri, the koyukkuri will actively cheer their parent, even if their size prevents them from taking a more active stance.
