Resolves yes if by the end of 2029 at least one biological human has "cat girl ears". The ears must appear catlike (or at least cat girl like) and grant similar hearing to cats. This includes the ability to move to detect where sounds are coming from and to express emotions.

The ears do not have to be biological, they can also be mechanical. They can be permanent or removable. They don't have to grant other senses, eg touch.

This market uses "cat girl" in an inclusive pan-gender and non-agist sense.

I will not bet in this market.
