When Salty begins behaving oddly, Mark recommends that Caroline consult a cat therapist. Although the woman is a complete fruitcake ""not allowed to practice on people any more,"" she accurately pinpoints the problem as Richard's fear of caring for animals. He confesses that he suffered a childhood trauma at the hands of his teacher, Mrs. Fox, when both the class gerbil and rabbit died while in his care and she condemned him as an ""animal killer."" Annie, who has been fixed up by her mother on a blind date with a peculiar forest ranger, helps Caroline track down the retired Mrs. Fox and convince her to make amends with Richard. This doesn't work out quite as planned, since Mrs. Fox also bites the dust.
