What animal can Professor McGonagall transform into?

The story behind the answer

Cat is correct: Professor Minerva McGonagall is a registered Animagus who can transform into a silver tabby cat, notable for square markings around its eyes—like her glasses. She first appears this way on Privet Drive, silently observing the Dursleys before Hagrid arrives with baby Harry.

Becoming an Animagus is advanced Transfiguration that takes years and must be recorded with the Ministry. The chosen animal often mirrors personality: a cat fits McGonagall’s keen, precise, and independent nature. Memory tip: think “Minerva Meow‑gonagall” and picture a tabby with spectacles—whenever you imagine strict rules and sharp eyes at Hogwarts, it’s McGonagall the cat.
