Before you choose

Shape, movement and small-screen readability

Chonk is a rounded dark cat with green eyes, pink ear interiors and a magenta accent near the feet. The eyes carry much of the expression because the body occupies a compact, dark shape.

Sideways motion is clear

The directional rows turn the head and body into profile, with an upright tail and alternating paws. The running row repeats that side-facing movement rather than the frontal idle pose.

Watch the eyes and ears

The failed row folds the ears down and adds blue tears, with small bright marks above the head in some frames. Review instead angles the head and narrows the eyes. The cues are different even though both rows keep the cat low.

Before choosing

On the dark inspection background, the body outline is subtler than the green eyes. Try it against your actual wallpaper before using a small scale; a light background will separate the dark coat more strongly.

Compare with Maltese: Maltese uses a white body and heavy dark outline, creating the opposite light-dark balance without relying on colored eyes.
