"There's a Cat" is a clock and Pomodoro timer set inside a quiet, monochrome room — with a cat living in it. Keep it on the corner of your desk while you work. Every time you glance over, the cat is there. It's designed to sit quietly in the background, never getting in the way of your focus. ■ The cat's quiet day A silhouette cat lives freely inside the room. It yawns, grooms itself, gazes out the window, and curls up to sleep again. We've focused on the small details — twitching ears, a swaying tail — that bring a cat to life through shadow alone. ■ A clock you can watch The screen shows a large clock and a monochrome room. The lighting shifts through morning, noon, evening, and night, in sync with the real time of day. Rain comes and goes outside the window, and the ambient sounds of the room change with it. ■ Pomodoro timer A simple Pomodoro timer is built in to mark your focus and break sessions. The cat and the room stay center stage the whole time. Only a soft bell marks each interval. ■ Made for ・A calm clock to sit on your work desk ・A short cat-watching break between focus sessions ・A quiet view by your bed before sleep ・To gently add a cat's quiet presence to your day ■ Features ・A colorless world built from light and shadow alone ・Lighting that shifts naturally with the time of day ・Occasional rain and a gentle ambient soundscape ・Natural cat motion expressed entirely through silhouette ・Clock view and Pomodoro timer
