"Filming people with cats allowed the animals to soften everyone's hearts. While direct human interactions can be guarded, cats provide common ground, slowly dissolving boundaries," Lu says.

While short videos have showcased various aspects of cats, Lu emphasizes that the documentary aims to offer a more holistic view of the relationship between humans and cats.

Lu believes that capturing human emotions comes from observing daily habits. "How a person eats, sleeps, or walks, these routines reveal their true character. This is something I focus on," he says.

"We all have habits we overlook but when documented, they reveal deeper emotions and aspects of your inner self," Lu adds.

As a result, many of the documentary's interviewees were moved to tears when they saw the footage, recognizing details they had previously missed.
