Giovanni's Persian is one of Giovanni's Pokemon. It was always seen with its master and Giovanni actually seemed to care about Persian and was often seen petting it. In return Persian was very loyal to Giovanni and went with him wherever he went. Persian has never been seen in battle, instead being treated as a pet. Team Rocket's Meowth hates Persian because it was Giovanni's favorite Pokemon. It was stated by Meowth that he used to be the top cat, but was replaced by that "stuck up good for nothing" Persian.
Rica Matsumoto who plays Satoshi is the original Japanese-language version voices Giovanni's Persian in both the Japanese and English language versions of the Pokemon anime.
