"Well, if you don’t want a replacement, you can try this rat tonic."
— Ron Weasley being sold this potion in the Magical Menagerie[src]

Rat Tonic[3] was a healing potion for rats. It was used to treat ageing rats. It was sold in a small red bottle at the Magical Menagerie in Diagon Alley.[1]

History

A red bottle of Rat Tonic

During the 1990–1991 school year at Hogwarts School of Witchcraft and Wizardry, seventh-year students were taught how to brew Rat Tonic in Potions class by Professor Severus Snape.[3]

A bottle of Rat Tonic

In the summer of 1993, in Diagon Alley, when Ron Weasley took his pet rat Scabbers to the Magical Menagerie because he looked ill, the witch behind the counter suggested Rat Tonic. Before Ron could pay, Scabbers was attacked and chased out of the shop by Crookshanks. Ron and Harry Potter followed. Hermione Granger stayed at the shop to buy Crookshanks and the Rat Tonic, which she later passed on to Ron.[1]

Superlative Rat Tonic was presumably a more powerful form of Rat Tonic that was also sold in the Magical Menagerie.[4]
