Nibbles

Nibbles is a cat that can be encountered in Oxenfurt.

This cat inhabits the same house in which Geralt of Rivia meets Tamara Strenger for the first time. Before encountering Tamara, both Geralt and Nibbles will take their time staring at each other, as if a nonverbal conversation occurs between them.

This could indicate that cats recognize the mutated eyes of witchers and thus display interest and sympathy for their supposed conspecifics.
