Gerbils are small mammals of the order Rodentia, known for their tunnelling behaviour. They are known to typically be non-aggressive in nature.
Gerbils in the wizarding world
There is a Transfiguration which turns teacups to gerbils. This spell was taught to sixth year students at Hogwarts School of Witchcraft and Wizardry. When he first met with the Prime Minister of Muggles, Cornelius Fudge used the spell in order to prove himself to be a wizard. The Prime Minister later gave the gerbil to his niece as part of his attempt to rid himself of all reminders of his encounter with Fudge.
Another kind of gerbil is the fanged gerbil which is a gerbil with fangs. Augusta Longbottom once found a fanged gerbil in her handbag, as a joke by her husband. After that she always kept a mousetrap in her bag.
