Why it worked
The video likely worked due to the novelty of using an ostrich egg for a DIY pet treat, combined with satisfying ASMR-like visuals and sounds of the preparation process. The transformation of a large egg into a fine powder and the cats' positive reaction to the treat would also contribute to its shareability.
Summary
The video shows the process of turning an ostrich egg into a dehydrated powder for cat treats. The ostrich egg is cracked open, the contents are spread onto dehydrator trays, and then dehydrated. The dehydrated egg is then blended into a powder using a Magic Bullet blender and labeled with a Nelko label maker. Finally, the powder is sprinkled onto cat food, and cats are shown eating it.
