Brandy was an orange tabby cat that portrayed Spot on Star Trek: The Next Generation beginning with the sixth season. While Brandy was the "more smooth" cat, Monster, Bud, and Tyler are the other cats that played Spot. Brandy can also be seen in the end scenes of Star Trek Generations when Data finds her in the wreckage.
Brandy was trained by Rob Bloch and Karen Thomas-Kolakowski of Critters of the Cinema.
