Catherine

Catherine is Erwin Sikowitz's girlfriend in the episode Tori Tortures Teacher, but later dumped Sikowitz in a play that Tori Vega, Andre Harris, Jade West and Beck Oliver had brought him to, as she had moved to Florida, which Tori thought that was why he was depressed. Sikowitz didn't miss Catherine as she had saws on her neck.

"Cutest little creature you ever saw. Used to sit on my lap - hop around the apartment! Such a silly!"

- Erwin Sikowitz commenting on Catherine's pet cat Bunny in Tori Tortures Teacher

Catherine had a pet cat, (Tori thought Bunny was a rabbit) who Sikowitz loved and adored, but when the cat had left LA to go to Florida with Catherine, Sikowitz became very depressed, which effected his life and caused him great pain.
