She is seen not to be particularly slender, but not obese either.
When Nate Wright was working on becoming an art critic, he was working on not criticizing, but saying helpful comments to students artwork. His first subject was Caitlin. Nate thought that Caitlin was drawing a German Shepherd, but Caitlin got upset because she was painting for a self portrait. This made Ken Rosa come for a "teacher intervention."
She was very upset when Nate mistook her self-portrait for a breed of dog.
