The Litterbox of Life, also referred to as Mourning Harold — the Living Tomb, is an interactive cathuman grotto featuring paintings, a structure (also referred to as the Litterbox of Life), and objects composed, curated, and grafted by The Familial Order of the Cat. The structure features a library (holding several unique copies of Mourning Harold — the Play), an ossuary, and a Place Setting for Grief. In the present exhibition, the Litterbox of Life is set as a space for theory, however, at other times, it functions as a theater. The paintings on the wall, collectively referred to as “Lineage,” are forgeries (at various states of completion) of the Codex Cattus, an illuminated manuscript. Illuminated by a human and written (scented) by a cat (c. 300 CE), historical vignettes (from 2000 BCE to the present day) are depicted visually. Unfortunately, to this day, humans have proven unsuccessful in deciphering the text.
