Why it worked
The video uses a simple, visually engaging format with a popular subject (cats) and clear visual feedback (red X vs. green checkmark) that is easy to understand and share, making it highly rewatchable and suitable for short-form video platforms.
Summary
The video displays a series of colored squares labeled "PHOTO 1" through "PHOTO 8". Next to each square, a cat image is shown. For some photos, a red 'X' appears above the square, indicating a negative result, while for others, a green checkmark appears, indicating a positive result. The video cycles through these options without any spoken dialogue.
