Katie receives a letter from Ms. Lang (Madeline) offering her a job. When she goes up to the fifth floor to ask her about it, Ms. Lang tells her she has to work late and needs a cat sitter. She offers her $30 a night and Katie eagerly accepts. Ms. Lang then reveals that she has 217 cats and that they’re all extremely well trained. They bring Katie a cup of tea; one of them shows her how to use the TV remote; another is using a computer; and all of them use the bathroom rather than a litter box. Before she leaves, Ms. Lang gives Katie a fingerprint scanner that locks and unlocks everything in her apartment.
Katie initially enjoys a moment cuddling with cats all around her, but they quickly scatter and start causing trouble. They tear the apartment apart and one of them orders pizza. As Katie scrambles to control the cats, the buzzer goes off; the building manager, Mrs. Piper, is at the door to investigate the commotion. Cats are not allowed in the apartment, and Katie is worried she is going to get Ms. Lang in trouble. However, the cats hide once the door is opened and Katie claims she is just cleaning.
Katie gives up on trying to control the cats and resigns herself to the fact she will be fired when Ms. Lang gets home. As she thinks that things couldn’t get any worse, she realizes all the cats are gone. Moments later they show up carrying groceries, cleaning supplies, and tools. Many of the cats clean and repair the apartment, while others steal a couch from Mrs. Piper’s apartment below. Ms. Lang returns home at midnight and remarks that she has never seen the place so clean. She pays Katie and asks her to come back the same time the next night. When Katie gets home, a postcard from Bethany is waiting for her.
Katie continues to cat sit for Ms. Lang and the cats continue to cause immense amounts of trouble while demonstrating preternatural abilities. Katie attempts to explain the situation to Mr. B, but he doesn’t believe her and assumes she is exaggerating. He also suggests that learning the cats’ names might make them more likely to listen to her.
That night, she attempts to learn their names and what they can do. Their abilities include things like computer hacking, martial arts, understanding numerous languages, helicopter repair, lock-picking, getaway driving, and using smoke bombs.
Katie writes a letter to Bethany telling her about the cats and that she should have the money to pay for the final week of camp.
Katie tells her mom the cats are supervillain levels of evil. Her mom suggests she should check the database to see if there’s anything about cats. After struggling with their terrible Internet connection due to a very old router, the search yields no results.
Katie continues to struggle with the cats and receives several lovingly decorated postcards from Bethany throughout the next week. Katie’s mom suggests she takes a night off from cat sitting. Katie declines, as she needs the money for camp. Her mom offers to help for a night instead, and the two head up to the apartment. The cats behave perfectly while Katie’s mom is around, and Katie suspects they’re doing it on purpose. When Ms. Lang returns home that night, she gives Katie some chocolate she claims to have got from work.
Katie writes to Bethany about the cats being evil and plotting something. She asks for advice on how to deal with them and expresses excitement at being just six nights of cat sitting away from being able to afford camp. Bethany says that Katie should trick the cats by changing the time on the clock since they always clean up close to midnight. She also tells Katie there’s a boy at camp named Ben who she might have a crush on.
Katie goes to the pet store and uses some of her money to buy a bunch of cat toys for that night. The cats are very excited about the toys but are distracted by a news story about an explosion at Pure Organics Chocolate factory. The company has reportedly gone out of business after discoveries made during the explosion investigation revealing that the company’s owner, Lydia Staples, had been illegally hunting endangered animals in Africa and putting them on display in a secret office.
Later, one of Mrs. Bell’s children tells Katie that she saw a giant mouse on their apartment roof, and that the mouse gave her chocolate. At 10:00 pm, Katie enacts her plan to change the clocks. She changes the time to 11:50 pm, sending the cats into a panic. They quickly clean the apartment and wait patiently by the front door. When the cats realize what has happened and that they have been tricked, they feel endeared toward Katie.
These chapters include dramatic irony, where readers are privy to information that a character is not. Katie has not yet realized that the Mousetress is responsible for the attacks on New You Cosmetics or Pure Organics, or that Ms. Lang is the Mousetress. However, there are enough clues to piece it together at this point. Attentive readers may have noticed the caged bunnies in the juxtaposed images of the Mousetress and Katie in Chapter 1. Later that night, when Katie is on her balcony, the silhouette of someone in a mouse costume enters the apartment two stories above her. This links the Mousetress to the cosmetic factory and reveals that the Mousetress is someone in Katie’s building. Ms. Lang give Katie chocolate after she arrives home from “work” the night of the attack on the chocolate factory, and Marcie tells Katie a large mouse was climbing on their apartment building and that it gave her chocolate. This section of the text also establishes that Ms. Lang lives two floors above Katie. The clues link the Mousetress to the chocolate factory and Ms. Lang to the Mousetress.
With these connections in mind, a pattern emerges among the victims the Mousetress is targeting: Both New York Cosmetics and Pure Organics are associated with animal cruelty and abuse. The novel explores Animal Rights, Social Activism, and the Law, and suggests that the Mousetress may not actually be a villain. Additionally, Ms. Lang’s cats have a deeper meaning and function than just causing trouble. While they provide levity and fit the silly and comedic tone of the text, they also foreground the idea that animals are intelligent creatures that help human beings. By establishing this, the novel makes acts of animal abuse much more reprehensible.
Through the cats, Katie demonstrates what a positive relationship with animals can and should look like: She treats them with care, respect, and as beings with rights equal to hers. She and the cats form a mutually beneficial partnership and help one another when necessary.
Working as a cat sitter for Ms. Lang reveals Katie’s most positive attributes. Katie is resilient and resourceful. The 217 cats are unruly and stubborn, but Katie perseveres, returning again and again. She even rejects the opportunity of taking a night off, determined to earn the money for camp. Not only does she persevere; she adapts and uses different strategies to control the cats: She learns all their names and interests, buys them toys with her own money, and eventually realizes that the key to gaining their respect is to beat them at their own game by playing tricks on them. In this way, Katie shows initiative, independence, and kindness that make her worthy of becoming the Mousetress’s sidekick at the end of the novel.
