Domino is a main character of the seventh Felidae novel: Felipolis.
She's a beautiful female of cross origin. Her mother was a Blue Russian but her features display some differences: a more dark blue/deep gray colour of the fur and golden eyes (instead of being green as other Blue Russian).
Domino is the unlucky she-cat that according the will of her elder human master, inherited all her huge fortune attracting the greed of many people. Domino was hiding from the human Marc Forster (a man that worked for her master) that scared her. Francis is quickly attracted by the beauty of the female and decide to help her (despite having remorse and confused feeling because of his official mate Sancta).
After a number of events, Francis discover how Forster has planned to make the she-cat the official heir for the huge fortune, just to work behind the scene with the aim to enrich himself.
Francis meets again Domino inside the villa but this time the detective realize how it was the pretty cross to have killed two humans (the first was an human opponent of Forster and the second one was Lars Büttel, leader of the Animal Army, whose purpose was to use the Domino's fortune to fund his group) making them fall from the villa in two separate occasions.
The detective realizes that Domino is actually Herzl's daughter (thanks also the partial Carthusian features of Domino) and was working with his father at the realization of the Felipolis.
Francis faces Domino and his father when they have gathered their followers (including Sancta, that was attracted by the Herzl speeches while Francis was wounded after his first meeting with Forster). Domino laughs at Francis when the tomcat advises them about how dangerous and untrustworthy Marc Forster is. According Francis, the man, despite being aware of the cats's intelligence, has no feelings for them and plans to exploit the projects of Herzl and Domino to satisfy his own greed.
The fears of Francis materializes when Forster and his men, rather than bringing the cats to the Airbus ready to fly to Koroyama island, brings them into an abandoned complex with an old but working crematorium.
As predicted by Francis, Forster betrays the two cats and Domino and her father meet an ironic and painful death when Forster puts them into the crematorium and burns them alive: the same fate suffered by millions of deported Jews during the Third Reich's rule ( Herlz and Domino had seen a parallelism of their purpose with the pre-war Jewish Zionist dream of claiming a land as own country).
