Before you choose

Shape, movement and small-screen readability

Mochi suits a light, expressive companion: the cream coat leaves the eyes and pink ear interiors as the main accents. The face stays large even when the body crouches.

Movement versus rest

The side-running rows stretch Mochi into a low leap, while idle keeps the paws planted and changes the eyes. This produces a clearer change of activity than the small blink alone.

Read the failure pose

In the failed row, the ears fold downward and the body settles close to the floor. Review uses head tilts and a paw near the mouth instead. Compare those rows at your intended display size so a thoughtful pose is not mistaken for failure.

Before choosing

The pale body has a dark edge, but the cream face and paws can still blend into a pale wallpaper. Preview both your normal background and a dark one; increasing scale helps the facial changes remain visible.

Compare with Siam: Siam has a similar compact cat shape but a dark face mask and bright blue eyes, giving the facial area stronger color separation.
