The Change

The Change is the sudden awakening through which The Clan acquired intelligence, speech, and a new understanding of itself; it also explains how Maurice became more than an ordinary cat. What first seemed an inexplicable coincidence turns out to have a grim, personal cause: Maurice ate a rat that had already been changed by discarded magical material. The revelation joins the rats’ new moral world to Maurice’s past as a predator, and makes the Change both an origin story and the source of his guilt.

The Two Awakenings

Maurice remembers his own awakening as a break in ordinary animal awareness. One day, just after lunch, he looked into a puddle and recognized himself as himself. Before that moment he could hardly reconstruct how he had thought; his earlier mind seemed, by comparison, like a kind of soup. The new self-awareness was not something he had sought or understood. It simply arrived, leaving him to discover that his thoughts could continue and develop in ways they had not before.

The rats underwent the Change at about the same time. Maurice initially knows the consequence before its cause: he encounters rats capable of speech and realizes that they are educated in a way no ordinary rats are. When he jumps on one, it asks whether they can talk. Maurice’s new mind supplies an unfamiliar restraint: someone who can speak should not simply be eaten, at least not before being heard. That hesitation opens a relationship that changes his conduct as well as his understanding of the rats.

The Change does not make every member of The Clan alike. Hamnpork, the large and fierce rat who holds the position of head rat, is already old when it happens and resists the new intelligence, insisting that he is too old to change. Dangerous Beans, by contrast, is born just after the Change. He becomes the Clan’s exceptionally clever interlocutor with Maurice, while Hamnpork leaves that talking to him. Their difference shows the awakening unfolding across generations: some must accommodate an unsettling new condition, while others grow up inside it.

The University Dump

The physical setting behind the Change is the rubbish heap behind Wizards' University, where the rats live and find food. The institution’s discarded materials enter the animals’ lives as refuse: worn-out spell-books, the stubs of candles used in magic, and the remains of green, bubbling substances from cauldrons are thrown over the wall alongside tin cans, boxes, and kitchen waste. The wizards put up warnings identifying the rubbish as dangerous and toxic, but the rats could not read them before their awakening and were attracted to things such as candle ends.

Maurice’s own experience seems, at first, to rule out a simple explanation. He has never eaten from the dump, and his practical rule is to avoid anything that glows. He therefore has no obvious reason to have changed when the rats did. The narration identifies the timing as a mystery rather than claiming that Maurice knowingly encountered magical waste. His account of the heap also makes the Change inseparable from a material environment: the rats’ new life begins amid the discarded residue of human magic, mixed indiscriminately with ordinary garbage and food scraps.

Maurice’s Part in the Cause

The answer emerges much later, when Maurice is pressed about why he changed despite never eating the dump’s contents. He asks Peaches and Dangerous Beans whether they remember a large rat with a missing ear, a patch of white fur, a bad leg, and difficulty speaking. Peaches recognizes the description as belonging to a rat who had disappeared before she and Dangerous Beans met Maurice. Dangerous Beans remembers him as good and says that, once he got talking, he was wonderful company.

Maurice finally admits that he ate that rat. His confession is blunt: he consumed almost all of him, leaving the tail and the parts he found especially repellent, including the green, wobbling piece and an unidentified purple lump. He had been an ordinary hungry cat at the time, had not yet learned to think, and did not know that the rat was a person. The rat had eaten the magical material on the dump; by eating the rat, Maurice received the cause of his own Change indirectly. What looked like spontaneous awakening was therefore bound to an earlier act of predation, though Maurice committed it before he possessed the awareness that would later make such an act unthinkable to him.

Consequences and Meaning

This discovery revises the Change from a shared marvel into a chain of consequences. The rats’ exposure to the dump explains their transformation; the fate of the stammering rat connects that transformation to Maurice’s. The crucial link is not that Maurice broke his rule against eating glowing things, but that he ate an animal that had consumed the magical waste. His ignorance explains the act without undoing its cost: the rat who made Maurice’s awakening possible was also a victim of his former instincts.

Maurice’s response is not a clean absolution. He says that on dark nights he sometimes thinks he can hear the rat speaking beneath him, and the memory of the green substance remains bound up with the confession. Peaches answers that it happened a long time ago. When Dangerous Beans asks whether Maurice has eaten anyone recently, Maurice says he has not. The exchange distinguishes the act that caused the Change from the person Maurice has become since: he cannot reverse his past, but he now recognizes the moral boundary he once lacked the mind to perceive.

The Change thus gives the story two related beginnings. It creates a speaking, thinking Clan whose members can consider a future beyond ordinary animal life, and it gives Maurice the intelligence that allows him to treat those rats as people. Yet his own beginning is inseparable from a death he did not understand at the time. The awakening is both gift and inheritance: it opens the possibility of restraint and companionship, while forcing Maurice to reckon with the violence that brought him into that new world.
