McGonagalls' cat

The McGonagalls' cat was a pet of the McGonagall family. Isobel McGonagall learned her daughter Minerva was a witch when she started displaying small, but unmistakable, signs of magic, such as the cat doing the infant's bidding before she could even talk.

Behind the scenes

 * It is interesting to note that Minerva McGonagall had an affinity with cats since she was an infant; in her adulthood, Minerva's Patronus and Animagus shape was that of a cat.
