The majority of McQueen’s estate was placed in his Sarabande charitable trust. He suggested in his will that the money be used to fund bursaries or grants for students at Central St Martins College of Art and Design in London, where McQueen studied.
McQueen committed suicide in February last year.
Spencer Wisdom, solicitor and legacy manager at Battersea Dogs and Cats Home, said: "News of such a generous legacy is a lovely surprise and reaffirms the love McQueen had for dogs and cats. We know he would be so proud to see his donation helping to care for the thousands of dogs and cats at Battersea in need of new homes."
