Seville

Seville is a ginger tom.

The Fourth Apprentice

 * The patrol of Clan cats looking for whatever is blocking the water from the lake encounter Seville, along with two kittypet friends of his, Snowdrop and Jigsaw. They see two caged rabbits in Seville's Twoleg Nest's yard, and they want to eat the rabbits, but Seville stops them. He explains that he has nothing against the Clan cats, but that his housefolk would be very angry if any cats hunted the rabbits, and he heard about another tom who hunted his Housefolk's rabbits, and he got taken to the Cutter and was "Never the same again".
 * Later, Lionblaze and Dovepaw come back to find Seville and his friends, to ask them to help dismantle the beaver dam, as it is too much work to do with their small amount of warriors. Seville agrees, and he and his friends go back to the stream with the Clan cats. When offered some fresh-kill, he politely declines saying he already ate, and he seems a bit disgusted by  it. He bravely goes out onto the dam and helps dismantle it, and with him and the other kittypets pitching in, the warriors successfully break the dam and free the water.
