Yvonne (Almost Perfect)

Yvonne was Torchwood Three's cat from early 2000 until a few weeks after Ianto Jones joined the team.

Yvonne was extremely close to Jack Harkness, who was very upset at her death. He ordered Ianto to check Myfanwy's stool samples for three months to see if she had eaten her. The cat ended up at a restaurant in Cardiff who took her in. (PROSE: Almost Perfect)
