A collaboration between Kao Japan, a chemical and cosmetics company, and Tekken resulted in a short promoting cat litter and liner products. The short uses the phrase "small news, big news," referring to cat urine and feces, respectively. Urinary issues in cats can often be detected through urine, making early health awareness important. The product features a special pellet litter and a tray with a drainage shelf. A pad at the bottom collects urine, allowing owners to monitor its volume and color. This helps identify potential health issues, something standard litter does not allow.
