Katie is in a much better mood after meeting Marie and hearing Ms. Lang’s animal rights speech at the protest. Before heading to Ms. Lang’s to cat sit, she stops by the bodega to pick up some cat treats, and Mr. B gives them to her on the house. Katie asks how he manages to stay in business when he is constantly giving things away. He reveals that his brother is billionaire Benito Benton: When their grandparents passed away, they each received half of the money. Mr. B spent lots of his money buying the building and giving away donations because he likes to do things that make him happy, rather than to make money.
Katie spends the night playing boardgames with the cats. At midnight, there is no sign of Ms. Lang. They turn on the news and discover that the Mousetress has been caught by the Eastern Screech.
At first, Katie denies that it could mean Ms. Lang is the Mousetress. However, the cats reveal a secret room containing computers, files, a large map of the city, and a spare Mousetress costume. The cats encourage Katie to put the costume on, and they show her blueprints of the city’s prison. After putting it on and making some adjustments, Katie and the cats head out to save Ms. Lang.
As they sneak out of the building, Mrs. Piper sees Katie in the Mousetress costume and gets scared. The cats show Katie that Ms. Lang has a secret jet hidden on the roof of their building, and one of the cats is able to pilot it. On the way to the prison, they review their strategy. They believe there will only be six guards on duty. The plan involves some of the cats creating a distraction while others shut down the alarm system. Meanwhile, Katie will use one of Mousetress’s gadgets to open the lock. However, when they arrive at the prison, it is overrun by guards wanting to see the Eastern Screech, who is also keeping watch.
Katie devises a new plan. They piece together a fake Eastern Screech costume and have some of the cats pretend to be him. While the guards are distracted, one of the cats sews their pants together, taking a large group of them out.
With the guards out of the way, the cats use a batch of mechanical mice to distract the Eastern Screech. Meanwhile, Katie and another cat sneak past and disable the lasers surrounding Madeline’s cell. Before they can open the cell, the Eastern Screech returns. Katie sends a series of cat squads at him, but he easily defeats them. He calls the Mousetress evil and pathetic. Katie tells him the Mousetress was just trying to help animals. The Eastern Screech admits that he already knows this but doesn’t care because capturing her is great press and has helped his Yelp rating. As he talks, a cat above him drops a glass container on his head, knocking him out.
Katie attempts to open the cell door. Police Chief Pardo shows up and informs her she will not be able to open the door by herself because it requires two keys and two authorized fingerprints at the same time. He also claims to know that the Mousetress was just helping animals and admits to being a fan of her work. However, he cannot help because the only other people authorized to open the cell are the mayor and the warden, and neither of them will be convinced to let her go.
Katie realizes that she can use the fingerprint scanner Ms. Lang gave her. With the locks in her apartment, she can copy Police Chief Pardo’s fingerprint, giving them a way to activate both locks at the same time. The door opens and Katie and Ms. Lang make their escape.
The next day, Katie goes to see Ms. Lang, who says she’s going to take a break from being the Mousetress for a little while to focus on fighting injustice during the day. She gives Katie the rest of the money she needs for camp, along with her own pair of Mousetress goggles and a card that grants her a lifetime of free food from a fancy vegan restaurant called Straight from the Farm. She can do this because she owns the restaurant and tells Katie she will get a share when she turns 18 as well.
A few days later, Katie receives another postcard from Beth. She doesn’t read it right away because she is heading out to learn how to skateboard with Marie. The postcard talks about a superhero day at camp. The Eastern Screech and Stainless Steel showed up, and Beth likes both now.
Katie decides not to go to camp and starts saving for vet school instead. The novel ends with Mr. B telling Ms. Lang that he knew Katie would make a good sidekick, and Ms. Lang confirming that she will be the best.
Much of the action revolving around the cats and their intelligence in these chapters is comedic. The cats work as a deus ex machina, where an improbable element steps in to neatly wrap things up. The cats also develop the novel’s ideas about animal rights. Katie is able to work so effectively with the cats because of the relationship she has established with them over the previous weeks. She has learned their names and specific abilities, and has built a level of mutual trust and respect that allows them to function as a team capable of breaking the Mousetress out of a heavily guarded prison. This working relationship between humans and animals is in stark contrast to the one Ms. Lang describes at the carriage horse mistreatment protest. It provides a model for what a healthy and positive, if exaggerated, dynamic between humans and animals could look like.
The final chapter reiterates how much Katie and Bethany have changed over the summer. Another postcard arrives from Bethany, but unlike before, Katie does not rush to open it. Instead, she opts to spend time with Marie, with whom her new interests and experiences are more closely aligned. Bethany’s postcard is devoid of the glitter and stickers that marked the girls’ closeness before, and reveals how much each girl has changed. For example, Bethany writes that the Eastern Screech showed up at camp for superhero day—“[he’s] really not that bad! Kinda cute almost” (204). At the beginning of the novel, Katie and Bethany are aligned in their dislike for the Eastern Screech, and Katie’s dislike has only grown stronger. Katie has learned to see through the artifice of his popularity and reputation, and knows that he is a fraud, while Bethany has simply gained an interest in boys (“kinda cute almost”). However, Bethany’s postcard is not unfriendly. This suggests that Katie and Bethany will remain friends, just not in the same way as before.
These final chapters complicate the novel’s depiction of wealth inequality. Up until now, the novel’s apparently wealthy figures, such as the Mousetress’s targets, are bad people. This links wealth with immorality. Additionally, the early chapters focus on Katie and her mom’s struggle with money, suggesting that it is immoral to amass extreme wealth in a world where poverty exists. In the final section, the revelation that Mr. B and Ms. Lang have lots of money reframes this reading. To a degree, it undercuts the novel’s critique of wealth inequality. The fact that Mr. B spent his billion dollars helping people suggests that there are good ways to make use of extreme wealth—especially when compared to the other examples of wealth in the text. Likewise, at the end of the novel, Ms. Lang hires Katie as her sidekick, provides her with unlimited free meals from her chain of vegan restaurants, and promises to make her a partner when she turns 18. This is another example of how wealthy people can be kind.
A potential critique is that the ending suggests a shallow and ineffective solution to inequity. Ms. Lang coming to Katie’s rescue implies that wealthy people are the answer to poverty. This would make poor people reliant on wealthy philanthropists, a solution that doesn’t address systemic issues such as unequal access to education and wages.
